Returning a 404 for this URL is the correct behavior, since it has /@workflow twice and is not a correct URL for the endpoint.

To fix this we would need to understand what steps you take in Volto that cause it to make this request. I don't think we can investigate further unless you provide more detailed steps to reproduce the problem.
