      Error Code Definitions

      Key getCode Error Code Description
      INVALID_PARAMETER 4096 0x1000 Invalid parameter.
      Suggested solution: Check whether the parameter values passed in meet the requirements. For example, check whether the correct types of values were passed in.
      INVALID_OPERATION 4097 0x1001 Invalid operation.
      Suggested solution: Check whether the API was called correctly. For example, if you call publish before room entry, this error will be returned.
      NOT_SUPPORTED 4098 0x1002 If this error is returned when you call an API, it indicates the current browser does not support the API.
      DEVICE_NOT_FOUND 4099 0x1003 This error is returned when the SDK attempts to capture data from the mic or camera but cannot find a mic or camera.
      Suggested solution: Ask the user to check whether the mic or camera functions properly. We recommend you add device check logic to your project. For details, see Environment and Device Check Before Calls.
      INITIALIZE_FAILED 4100 0x1004 LocalStream.initialize() failed to capture data. For details, see Solution.
      SIGNAL_CAHNNEL_SETUP_FAILED 16385 0x4001 Failed to establish a signaling channel. The reason is often related to accounts. For details, see Account Errors.
      SIGNAL_CHANNEL_ERROR 16386 0x4002 Signaling channel error.
      ICE_TRANSPORT_ERROR 16387 0x4003 ICE transport connection error. This indicates an error occurred with the audio/video transmission channel. This is usually caused by UDP port exceptions. For example, if the ports used for data transfer are blocked by a user’s computer or router firewall, this error will be returned. For the ports used for data transfer, see Dealing with Firewall Restrictions.
      JOIN_ROOM_FAILED 16388 0x4004 Failed to enter the room. For details, see Room Entry Errors
      CREATE_OFFER_FAILED 16389 0x4005 Failed to create SDP offer.
      SIGNAL_CHANNEL_RECONNECTION_FAILED 16390 0x4006 Failed to reconnect WebSocket to the signaling channel.
      • When WebSocket is disconnected, the SDK will try to reconnect it. If multiple retries fail, it will return this error.
      • Suggested solution: Ask users to check their network connection and enter the room again.
      UPLINK_RECONNECTION_FAILED 16391 0x4007 Upstream peer reconnection failed.
      • When upstream peers are disconnected, the SDK will try to reconnect them. If multiple retries fail, it will return this error.
      • Suggested solution: Ask users to check their network connection and publish or enter the room again.
      DOWNLINK_RECONNECTION_FAILED 16392 0x4008 Downstream peer reconnection failed.
      • When downstream peers are disconnected, the SDK will try to reconnect them. If multiple retries fail, it will return this error.
      • Suggested solution: Ask users to check their network connection and enter the room again.
      REMOTE_STREAM_NOT_EXIST 16400 0x4010 The remote stream does not exist.
      • If user A tries to subscribe to the stream of user B, but user B has stopped publishing his or her stream, this error will be returned.
      • You don’t need to handle this error.
      CLIENT_BANNED 16448 0x4040 The user was removed from the room for one of the following reasons:
      • A user with the same username entered the room. Note: Avoid repeated room entry with the same username because it will cause an error.
      • The account admin called a server-side API to remove the user from the room.
      SERVER_TIMEOUT 16449 0x4041 Media transmission service timed out.
      SUBSCRIPTION_TIMEOUT 16450 0x4042 Remote stream subscription timed out.
      PLAY_NOT_ALLOWED 16451 0x4043 Autoplay blocked.
      DEVICE_AUTO_RECOVER_FAILED 16452 0x4044 Failed to resume capturing data from the mic/camera. This is an error event for LocalStream.
      • When a device change is detected (for example, if the camera or mic used for publishing is disconnected or reconnected), the SDK will try to resume capturing. If it fails, this error will be returned.
      • Suggested solution: Notify users of the failure and ask them to check if their devices are disconnected or occupied by other applications.
      • You can also add a retry button to the UI for users to manually resume capturing.
      START_PUBLISH_CDN_FAILED 16453 0x4045 Failed to publish to CDN.
      STOP_PUBLISH_CDN_FAILED 16454 0x4046 Failed to stop publishing to CDN.

      SWITCH_ROLE_FAILED 16458 0x404a Failed to switch user roles.
      UNKNOWN 65535 0xFFFF Unknown error.
