  Any error that the operation doesn't list separately, such as 500 Internal Server Error. Errors are returned as Problem Details for HTTP APIs as specified in [RFC 9457](https://www.rfc-editor.org/rfc/rfc9457). The example is only an illustration of a 500 Internal Server Error: in an actual response, the title names the operation that failed, such as "IssueVC failed", and the detail is the node's error message.
