Error Codes

No data will be returned if an API fails to be called. You can locate the error cause based on the error code of each API. When an API call fails, HTTPS status code 4xx or 5xx is returned. The returned message body contains the specific error code and error information. If you fail to locate the cause of the error, contact technical support and provide the error code for troubleshooting.

Error Response Body Format

If an error occurs during API calling, an error code and error message will be displayed. An error response body is shown as follows:

{
    "error_msg": "The input parameter is invalid.",
    "error_code": "AIS.0101"
}

In the error response, error_code indicates an error code, and error_msg describes the error.

APIG

APIG.0101

The API does not exist or has not been published in the environment.

The API does not exist or has not been published.

  • Check whether the API URL is correct. For example, check whether the project ID is included in the URL.

  • Check whether the region in the URI is the same as that configured for calling the service by referring to Endpoint.

  • Check whether the HTTP request method (such as POST and GET) is correct.

  • For details about the URI, see the corresponding API page.

APIG.0201

Backend timeout.

Request timed out.

  • Check whether the original API call requests are excessively frequent. If so, check the return value in the code and resend the requests later (for example, 2 to 5 seconds later). You can also check whether the result of the previous request is returned at the backend. After the result of the previous request is returned, send the next request.

  • Check whether the image is too large or the network delay is too long. If the image is too large, compress the image in proportion while ensuring the image definition. If the network delay is long, you can increase the network transmission speed.

APIG.0301

Incorrect IAM authentication information.

The IAM authentication information is incorrect.

  • decrypt token fail: The token fails to be parsed.

  • token expires: The token has expired.

  • x-auth-token not found: The x-auth-token parameter is not found.

  • If the token fails to be parsed, check the method for obtaining the token, whether the request body is correct, whether the token is correct, and whether the environment for obtaining the token is the same as the environment for calling the token.

  • If the token expires, obtain a new token that is valid permanently.

  • Check whether the spelling of X-Auth-Token in the request header is correct.

APIG.0308

The throttling threshold has been reached: policy user over ratelimit,limit:XX,time:1 minute.

The request exceeds the default rate limit of the service.

Rectify the fault using either of the following methods:

  • Use the retry mechanism to rectify the fault by checking the return value in the code and retrying the requests after a short period of time (for example, 2 to 5 seconds).

  • You can also check whether the result of the previous request is returned at the backend. After the result of the previous request is returned, send the next request.
