Errors returned with HTTP status code 203

CallbackFailed

• Error message: Get image info failed.

  Cause: OSS failed to obtain the information about the image. The image may fail to be uploaded or is deleted.

  Solution:

  • If the image failed to be uploaded, call the PutObject operation to upload the image again.
  • Check whether the image is automatically deleted based on lifecycle rules or manually deleted by other authorized users.
• Error message: Too many callback requests.

  Cause: Too many callback requests are being processed by OSS.

  Solution: Send the callback request later.

• Error message: Cost too long time.

  Cause: OSS determines that the request times out because the callback server takes more than 5 seconds to process the request.

  Solution: To ensure that the callback server can process a request and return the result to OSS within 5 seconds, we recommend that you change the processing logic of the callback server to asynchronous.

• Error message: Response body is not valid json format.

  Cause: The message body of the response returned by the callback server is not in the JSON format.

  Solution: See Upload callback common errors and troubleshooting to handle the problem.

• Error message: Error Status : 400.User server return too long content-length value.

  Cause: The response returned by the application server to OSS does not contain the Content-Length header. The size of the response body is larger than 1 MB.

  Solution: Make sure that the response returned by the application server to OSS contain the Content-Length header and the size of the response body does not exceed 1 MB.

  For example, the following sample response contains the Content-Length header. The body of the response is {"a":"b"}, which does not exceed 1 MB in size.
