Error Code
Last Updated：2020-07-20
When there is an error in the user's access to the BLB, the corresponding error code and error information will be returned to the user, which is convenient for the user to locate the problem and make appropriate treatment. The detailed error information is returned through Response Body in case of a request error, and the following format is followed:
| Parameter name | Type | Description |
|---|---|---|
| code | String | Error code |
| message | String | Err description |
| requestId | String | RequestID of this request |
Example:
{
"requestId" : "ae2225f7-1c2e-427a-a1ad-5413b762957d",
"code" : "NoSuchKey",
"message" : "The resource you requested does not exist"
} BCE Common Error Code
| Error code | Err description | HTTP status code | Semantics |
|---|---|---|---|
| AccessDenied | Access denied. | 403 Forbidden | No permission to access the corresponding resources |
| InappropriateJSON | The JSON you provided was well-formed and valid, but not appropriate for this operation. | 400 Bad Request | The JSON format in the request is correct, but doesn't meet the requirements semantically, such as lack of one necessary item or value type mismatch. For consideration of compatibility, all unrecognizable items should be ignored directly, and this error should not be returned. |
| InternalError | We encountered an internal error. Please try again. | 500 Internal Server Error | All other undefined errors should not be utilized when there are specific corresponding other types of errors (including generic and service customized errors). |
| InvalidAccessKeyId | The Access Key ID you provided does not exist in our records. | 403 Forbidden | The Access Key ID does not exist. |
| InvalidHTTPAuthHeader | The HTTP authorization header is invalid. Consult the service documentation for details. | 400 Bad Request | The format of Authorization header is wrong. |
| InvalidHTTPRequest | There was an error in the body of your HTTP request. | 400 Bad Request | The HTTP body format is wrong. E.g. inconformity with the designated Encoding, etc. |
| InvalidURI | Could not parse the specified URI. | 400 Bad Request | The URI format is incorrect, such as mismatch of some service-defined keywords. For ID mismatch and other problems, a more specific error code should be defined, such as NoSuchKey. |
| MalformedJSON | The JSON you provided was not well-formed. | 400 Bad Request | The JSON format is invalid. |
| InvalidVersion | The API version specified was invalid. | 404 Not Found | The version number of URI is invalid. |
| OptInRequired | A subscription for the service is required. | 403 Forbidden | The corresponding service is not subscribed. |
| PreconditionFailed | The specified If-Match header doesn't match the ETag header. | 412 Precondition Failed | ETag not matched |
| RequestExpired | Request has expired. Timestamp date is XXX. | 400 Bad Request | The request has timed out. |
| IdempotentParameterMismatch | The request uses the same client token as a previous, but non-identical request. | 403 Forbidden | The API parameters corresponding to clientToken are non-identical. |
| SignatureDoesNotMatch | The request signature we calculated does not match the signature you provided. Check your Secret Access Key and signing method. Consult the service documentation for details. | 400 Bad Request | The signature attached in the Authorization header is inconsistent with the server authentication. |
