◆ ERROR_CODE_TYPE

enum agora::ERROR_CODE_TYPE

Error code.

Enumerator
ERR_OK 

0: No error occurs.

ERR_FAILED 

1: A general error occurs (no specified reason).

ERR_INVALID_ARGUMENT 

2: An invalid parameter is used. For example, the specific channel name includes illegal characters.

ERR_NOT_READY 

3: The SDK module is not ready. Possible solutions:

  • Check the audio device.
  • Check the completeness of the application.
  • Re-initialize the RTC engine.
ERR_NOT_SUPPORTED 

4: The SDK does not support this function.

ERR_REFUSED 

5: The request is rejected.

ERR_BUFFER_TOO_SMALL 

6: The buffer size is not big enough to store the returned data.

ERR_NOT_INITIALIZED 

7: The SDK is not initialized before calling this method.

ERR_NO_PERMISSION 

9: No permission exists. Check if the user has granted access to the audio or video device.

ERR_TIMEDOUT 

10: An API method timeout occurs. Some API methods require the SDK to return the execution result, and this error occurs if the request takes too long (more than 10 seconds) for the SDK to process.

ERR_CANCELED 

11: The request is canceled. This is for internal SDK use only, and it does not return to the application through any method or callback.

ERR_TOO_OFTEN 

12: The method is called too often.

ERR_BIND_SOCKET 

13: The SDK fails to bind to the network socket. This is for internal SDK use only, and it does not return to the application through any method or callback.

ERR_NET_DOWN 

14: The network is unavailable. This is for internal SDK use only, and it does not return to the application through any method or callback.

ERR_NET_NOBUFS 

15: No network buffers are available. This is for internal SDK internal use only, and it does not return to the application through any method or callback.

ERR_JOIN_CHANNEL_REJECTED 

17: The request to join the channel is rejected.

  • This error usually occurs when the user is already in the channel, and still calls the method to join the channel, for example, joinChannel.
  • This error usually occurs when the user tries to join a channel during startEchoTest. Once you call startEchoTest, you need to call stopEchoTest before joining a channel.
  • The user tries to join the channel with a token that is expired.
ERR_LEAVE_CHANNEL_REJECTED 

18: The request to leave the channel is rejected.

This error usually occurs:

  • When the user has left the channel and still calls leaveChannel to leave the channel. In this case, stop calling leaveChannel.
  • When the user has not joined the channel and still calls leaveChannel to leave the channel. In this case, no extra operation is needed.
ERR_ALREADY_IN_USE 

19: Resources are occupied and cannot be reused.

ERR_ABORTED 

20: The SDK gives up the request due to too many requests.

ERR_INIT_NET_ENGINE 

21: In Windows, specific firewall settings can cause the SDK to fail to initialize and crash.

ERR_RESOURCE_LIMITED 

22: The application uses too much of the system resources and the SDK fails to allocate the resources.

ERR_INVALID_APP_ID 

101: The specified App ID is invalid. Please try to rejoin the channel with a valid App ID.

ERR_INVALID_CHANNEL_NAME 

102: The specified channel name is invalid. Please try to rejoin the channel with a valid channel name.

ERR_NO_SERVER_RESOURCES 

103: Fails to get server resources in the specified region. Please try to specify another region when calling initialize.

ERR_TOKEN_EXPIRED 

109: The token expired due to one of the following reasons:

  • Authorized Timestamp expired: The timestamp is represented by the number of seconds elapsed since 1/1/1970. The user can use the Token to access the Agora service within 24 hours after the Token is generated. If the user does not access the Agora service after 24 hours, this Token is no longer valid.

  • Call Expiration Timestamp expired: The timestamp is the exact time when a user can no longer use the Agora service (for example, when a user is forced to leave an ongoing call). When a value is set for the Call Expiration Timestamp, it does not mean that the token will expire, but that the user will be banned from the channel.

    Deprecated** Deprecated as of v2.4.1. Use CONNECTION_CHANGED_TOKEN_EXPIRED(9) in the onConnectionStateChanged callback instead.

ERR_INVALID_TOKEN 

Deprecated Deprecated as of v2.4.1. Use CONNECTION_CHANGED_INVALID_TOKEN(8) in the onConnectionStateChanged callback instead.

110: The token is invalid due to one of the following reasons:

  • The App Certificate for the project is enabled in Console, but the user is still using the App ID. Once the App Certificate is enabled, the user must use a token.
  • The uid is mandatory, and users must set the same uid as the one set in the joinChannel method.
ERR_CONNECTION_INTERRUPTED 

111: The internet connection is interrupted. This applies to the Agora Web SDK only.

ERR_CONNECTION_LOST 

112: The internet connection is lost. This applies to the Agora Web SDK only.

ERR_SIZE_TOO_LARGE 

114: The size of the sent data is over 1024 bytes when the user calls the sendStreamMessage method.

ERR_BITRATE_LIMIT 

115: The bitrate of the sent data exceeds the limit of 6 Kbps when the user calls the sendStreamMessage method.

ERR_TOO_MANY_DATA_STREAMS 

116: Too many data streams (over 5 streams) are created when the user calls the createDataStream method.

ERR_STREAM_MESSAGE_TIMEOUT 

117: The data stream transmission timed out.

ERR_SET_CLIENT_ROLE_NOT_AUTHORIZED 

119: Deprecated as of v3.7.0. Use CLIENT_ROLE_CHANGE_FAILED_REASON reported in onClientRoleChangeFailed instead.

ERR_DECRYPTION_FAILED 

120: Decryption fails. The user may have used a different encryption password to join the channel. Check your settings or try rejoining the channel.

ERR_CLIENT_IS_BANNED_BY_SERVER 

123: The user is banned by the server. This error occurs when the user is kicked out the channel from the server.
