If you pass non-existing parameters in body to the volume API's, then it returns 404 HTTPNotFound error.
According to api guidelines [1] it should return 400 HTTPBadRequest.

This bug is no longer valid. Schema validation has been available in the v3 API since Rocky, and that's the only API we have at this point.
