If so, I'd generally claim this is an issue with the client you're using: I think clients generally should not do parameter validation themselves. They will always be less able to do validation than the server is, even though server validation is not especially sophisticated right now. If/when we have a formal Python API client, it is very unlikely to perform client validation. Does client validation provide any advantage?

yeah that does not make sense and would cause nothing to work I'm pretty sure

(Wait I may be crazy.)

The client is doing validation of the response including presence of fields and their type.
