Error Codes

If an error occurs during API calling, no result is returned. You can locate the cause of an error using the error codes of each API. When an API call fails, HTTPS status code 4xx or 5xx is returned. The returned message body contains a specific error code and error message. If you fail to locate the cause of the error, contact the Huawei Cloudcustomer service and provide the error code for troubleshooting.

Format of an Error Response Body

If an error occurs during API calling, an error code and a message will be displayed. The following shows an error response body.

{ 

    "error_code": "SIS.0032",
    "error_msg": "'audio_format' is invalid"
}

In the response body, error_code is an error code, and error_msg provides information about the error.

Error Code Description

If an error code starting with APIGW is returned after you call an API, rectify the fault by referring to the instructions provided in API Gateway Error Codes.

Error Code	Description	Solution
SIS.0001	Connection error. For example, the connection to OBS or Redis is incorrect.	Contact technical support engineers.
SIS.0003	The token does not contain user information, the agency has been created, or an internal error occurs.	Contact technical support engineers.

SIS.0101	The authentication token is abnormal.	Check whether the value of X-Auth-Token in the request header is correct. Check whether the token request parameters are correct. Check whether the value of projectId in the URL is correct. When obtaining a token, add the scope parameter to the request to obtain a project-level token. Do not use a global token when calling SIS.
SIS.0102	Authentication information is missing.	Check whether the X-Auth-Token field in the request header exists.

Ensure that the value of audio_format is valid and is same as the format of the audio to be identified. If you are not sure about the value of audio_format when calling the Long Audio Transcription API, set the value to auto for debugging. If the error message data base64 encode invalid is displayed, check whether the character string is correct after Base64 encoding, for example, whether there are extra spaces or incorrect characters.

SIS.0302	The internal service is abnormal.	Contact technical support engineers.
SIS.0303	Failed to connect to the engine.	Try again. If the problem occurs multiple times, contact professional engineers.
SIS.0304	Audio waiting timed out.	This error is reported if the client does not send a voice message for a long time and the server does not receive the voice message within 20 seconds. Reduce the data sending interval. Check the code to view whether there is too much idle time after an audio segment is sent. Check whether an ending request is sent and the client is closed.
SIS.0305	An exception occurred during speech recognition.	Try again or contact technical support engineers.
SIS.0306	An exception occurred during speech recognition.	Try again or contact technical support engineers.
SIS.0307	An exception occurred during speech recognition.	Try again or contact technical support engineers.
SIS.0309	The real-time speech recognition audio duration exceeds the upper limit.	Check whether the audio duration is supported. In the short-stream mode, the audio duration cannot exceed 60 seconds. In the continue-stream or sentence-stream mode, the audio duration cannot exceed 5 hours.
SIS.0401	An exception occurred during audio synthesis.	Try again or contact technical support engineers.
SIS.0402	The input sample_rate parameter for TTS is invalid.	Check whether the input sample_rate for TTS matches the sampling ratio supported by the value range of property.
