Errors are accompanied by three error headers (v9.1):
Castor‑System‑Error‑Code- The request error code (if applicable). This code is usually a 4xx or 5xx HTTP response code, but it may not match the response code on the request.Castor‑System‑Error‑Text- The request error description (if applicable). Provides a human-readable description of the error.Castor‑System‑Error‑Token- A unique error token for the specific error path (if applicable). Provides a parsed token that uniquely identifies the error.
The storage cluster can return the following responses when the content length header does not match the actual content length, the specified content cannot be written to the cluster, or if there is a problem with the WRITE request itself.
