ERROR_CODE

// Usage:
// 1. API call error
trtc.startLocalVideo().catch(error => {
 if (error.code === TRTC.ERROR_CODE.DEVICE_ERROR) {}
});
// 2. Non-API call error, the error that the SDK cannot recover after internal retry
trtc.on(TRTC.EVENT.ERROR, (error) => {
   if (error.code === TRTC.ERROR_CODE.OPERATION_FAILED) {}
});

Description: The parameters passed in when calling the interface do not meet the API requirements.
Handling suggestion: Please check whether the passed-in parameters comply with the API specifications, such as whether the parameter type is correct.

extraCode	Description
5001	The required parameter is not passed in
5002	The parameter type is incorrect
5003	The parameter is empty
5004	The parameter instance is incorrect
5005	The parameter value is out of range
5006	The parameter value is less than 0
5007	The parameter value is less than the minimum value
5008	The parameter value is greater than the maximum value
5009	The elementId cannot be found on the page or was not found on the page when searching
5010	The parameter passed in is not of type HTMLElement
5011	streamId does not meet the specifications
5012	The range of the incoming roomId does not comply with the specifications [1, 4294967294]
5013	The strRoomId type passed in is not a legal string
5014	When the userId is not '*', a streamType needs to be passed in
5015	roomId or strRoomId not passed in, one of them must be passed in
5016	roomId must be a numeric type. Currently, a string type has been passed in. If you need to use a string as the room id, please use strRoomId

Description: The prerequisite requirements of the API are not met when calling the interface.
Handling suggestion: Please check whether the calling logic complies with the API prerequisite requirements according to the corresponding API document. For example: 1. Switching roles before entering the room successfully, 2. The remote user and stream being played do not exist.

extraCode	Description
5101	The API is called without entering the room, such as startRemoteVideo muteRemoteAudio switchRole and other APIs need to be called after entering the room
5102	The remote user does not exist, for example, when startRemoteVideo is called, the userId passed in corresponds to a remote user who is not in the room.
5103	The remote stream type does not exist, for example, when startRemoteVideo is called, streamType = TRTC.TYPE.STREAM_TYPE.SUB is passed in, but the corresponding remote user does not share the screen.
5104	Repeatedly calling the API, for example, after entering the room successfully, enterRoom interface is called again.
5105	Calling the API without the camera being enabled. For example, virtual background plugins require the camera to be enabled for use.
5106	Calling the API without the microphone being enabled. For example, AI noise reduction plugins require the microphone to be enabled for use.

Description: The current environment does not support this function, indicating that the current browser does not support calling the corresponding API.
Handling suggestion: Usually, TRTC.isSupported can be used to perceive which capabilities the current browser supports. If the browser does not support it, you need to guide the user to use a browser that supports this capability. Reference: Check Environment and Device Before Calls

extraCode	Description
5201	The current page protocol is not HTTPS, and the audio and video capture (pushing, linking) capabilities are not supported
5202	The current browser does not support WebRTC capabilities, the browser version is too low, or
5203	The browser does not support H264 encoding capability
5204	The browser does not support H264 decoding capability
5205	The browser does not support screen sharing capability
5206	The browser does not support small stream encoding capability
5207	The browser does not support SEI receiving and sending capabilities
5208	The browser does not support WebGL.
5209	The current version of the browser does not support this feature. Please upgrade to the latest version.

Description: Exception occurred when obtaining device or capturing microphone/camera/screen sharing.

The following API will throw this error code when an exception occurs: trtc.startLocalAudio trtc.startLocalVideo trtc.startScreenShare

Suggestion: Guide the user to check whether the device has a camera and microphone, whether the system has authorized the browser, and whether the browser has authorized the page. It is recommended to increase the device detection process before entering the room to confirm whether the microphone and camera exist and can be captured normally before proceeding to the next call operation. Usually, this exception can be avoided after the device check. Check Environment and Device Before Calls

If you need to distinguish more detailed exception categories, you can process according to the following extraCode:

extraCode	Description
5301	NotFoundError(DOMException) thrown by the browser Reason: The media device type that meets the request parameters cannot be found (including: audio, video, screen sharing). For example: The PC does not have a camera, but the browser is requested to obtain a video stream, which will report this error. Suggestion: It is recommended to guide users to check the camera or microphone and other external devices required for the call before the call.
5302	NotAllowedError(DOMException) thrown by the browser Reason: The user refused the microphone, camera, and screen sharing requests of the current browser instance. The permission of camera/microphone/screen sharing has been denied by system. Suggestion: Prompt the user to authorize the camera/microphone access before audio and video calls can be made. If the browser permission is denied by the system, rtcError will have rtcError.handler method, which can be called to jump to the System Permission Setting APP, so as to facilitate the user to open the permission.
5303	NotReadableError(DOMException) thrown by the browser Reason: Although the user has authorized the use of the corresponding device, due to errors that occurred on some hardware, browser, or webpage levels on the operating system, or other applications occupying the device, the device cannot be accessed by the browser. Suggestion: Handle according to the browser's error message, and prompt the user: "Unable to access the camera/microphone temporarily, please ensure that there are no other applications requesting access to the camera/microphone, and try again"
5303	NotReadableError(DOMException) thrown by the browser Reason: Although the user has authorized the use of the corresponding device, due to errors that occurred on some hardware, browser, or webpage levels on the operating system, or other applications occupying the device, the device cannot be accessed by the browser. Suggestion: 1-If this problem occurs with Windows Camera, the user will be directed to check whether the device is occupied. Only the camera of Windows system will be exclusive, but the microphone will not be exclusive. 2-If this error occurs with the microphone and camera of other systems, the user will be directed to check whether the device is normal or try to restart the browser.
5304	OverconstrainedError(DOMException) thrown by the browser Reason: The value of the cameraId/microphoneId parameter is invalid Suggestion: Check whether cameraId/microphoneId is the value returned by the device information acquisition interface
5305	InvalidStateError(DOMException) thrown by the browser Reason: The current page has not generated interaction, and the page is not fully activated Suggestion: It is recommended to turn on the camera and microphone after the user has clicked on the page to generate interaction
5306	SecurityError(DOMException) thrown by the browser Reason: The system security policy prohibits the use of the device Suggestion: Check whether the system restricts the use of the device, and recommend turning on the camera and microphone after the user clicks on the page to generate interaction
5307	AbortError(DOMException) thrown by the browser Reason: The device cannot be used due to some unknown reasons Suggestion: It is recommended to replace the device or browser, and recheck whether the device is normal
5308	Camera capture exception, after SDK retry, the capture cannot be restored. Reason: Camera exception or the user manually closes the capture permission of the browser Suggestion: Prompt the user that the camera capture is abnormal, and guide the user to check whether the camera is normal and whether there is a capture permission
5309	Microphone capture exception, after SDK retry, the capture cannot be restored. Reason: Microphone exception or the user manually closes the capture permission of the browser Suggestion: Prompt the user that the microphone capture is abnormal, and guide the user to check whether the microphone is normal and whether there is a capture permission

Reference: getUserMedia exception and getDisplayMedia exception

trtc.startLocalVideo(...).catch(function(rtcError) {
 if(rtcError.code == TRTC.ERROR_CODE.DEVICE_ERROR) {
   // Guide the user to check the device
   switch(rtcError.extraCode) {
     case 5301:
       // Can't find a camera or microphone, guide the user to check if the microphone and camera are working.
       break;
     case 5302:
       if (error.handler) {
         // Prompt the user the browser permission(camera/microphone/screen sharing) has been denied by system. The browser will jump to the System Settings APP, please enable the relevant permissions!
       } else {
         // Prompt the user to allow camera, microphone, and screen share capture permissions on the page.
       }
       break;
     // ...
   }
 }
})

Description: The exception that the SDK cannot solve after multiple retries under the condition of meeting the API call requirements, usually caused by browser or network problems.
The following interfaces will throw this error code when an exception occurs: enterRoom, startLocalVideo, startLocalAudio, startScreenShare, startRemoteVideo, switchRole
Handling suggestions:

• Confirm whether the domain name and port required for communication meet your network environment requirements, refer to the document Handle Firewall Restriction
• Other issues need to be handled by engineers. Contact us on telegram

extraCode	Description
5501	Firewall restriction: After multiple retries, the SDK still cannot establish a media connection, which will cause streaming and pulling to fail. Handling suggestions: Refer to the tutorial Handle Firewall Restriction
5502	Re-entering the room failed: When the user experiences a network outage of more than 30s, the SDK will try to re-enter the room to restore the call, but the re-entry may fail due to the expiration of userSig, and this error will be thrown. Handling suggestions: When encountering this error, you can use the latest userSig to call TRTC.enterRoom to enter the room again
5503	Re-entering the room failed: When the user experiences a network outage of more than 30s, the SDK will try to re-enter the room to restore the call, but the re-entry may fail due to the expiration of userSig, and this error will be thrown. Handling suggestions: When encountering this error, you can use the latest userSig to call TRTC.enterRoom to enter the room again

Description: The error code thrown when the API execution is aborted. When the API is called or repeatedly called without meeting the API lifecycle, the API will abort execution to avoid meaningless operations.
For example: Call enterRoom, startLocalXxx and other interfaces continuously, and call exitRoom without entering the room.
The following interfaces will throw this error code when an exception occurs: enterRoom, startLocalVideo, startLocalAudio, startScreenShare, startRemoteVideo, switchRole
Handling suggestions: Capture and identify this error code, then avoid unnecessary calls in business logic, or you can do nothing, because the SDK has done side-effect-free processing, you only need to identify and ignore this error code when catching it.

Description: Unknown error or undefined error
