Error Codes

If an API call fails, no result data is returned. You can locate the cause of the error according to the error code of each API. If an API call fails, HTTP status code 3xx, 4xx or 5xx is returned. The response body contains the specific error code and information.

Error Response Syntax

When an error occurs, the response header information contains:

  • Content-Type: application/xml

  • HTTP error status code 3xx, 4xx, or 5xx

The response body also contains information about the error. The following is an error response example that shows common elements in the Representational State Transfer (REST) error response body.

<?xml version="1.0" encoding="UTF-8"?>
<Error>
<Code>NoSuchKey</Code>
<Message>The resource you requested does not exist</Message>
<Resource>/example-bucket/object</Resource>
<RequestId>001B21A61C6C0000013402C4616D5285</RequestId>
<HostId>RkRCRDJENDc5MzdGQkQ4OUY3MTI4NTQ3NDk2Mjg0M0FB
QUFBQUFBYmJiYmJiYmJD</HostId>
</Error>

Table 1 describes the meaning of each element.
