Hi @Ashok Kumar 
perhaps I didn't make myself clear with my intention;

I want to be able to directly set metadata such as summary, responses, request parameters, etc. directly in the comment above each endpoint method (where I said "can I add metadata here?")

I don't mind if I have to make my own custom implementation to read these values, but I have no idea where to start right now, or whether I even should, perhaps there are already a solution available somewhere?

reason: The swagger spec generated is almost useless, because it does not specify the required parameters / payload for each respective endpoint, it only captures what is inside the UrlMap it seems.

Ideally I'd want to have my implementation of swagger to read the required request parameters / payload, but manually keeping docs updated through comments is a fine starter for my project, is any of this possible already or would I need to create a custom solution using %REST.API ?

EDIT: I just realized you're talking about using specification-first approach, I am talking about the opposite, implementation first, I'll look into going about the specification-first approach.

Thank you again for your help.

Thank you for your reply, I have already tried every option, None, Lax and even Strict again.

The error doesn't happen in the browser, in fact I don't see the error until I dig into the application error log or global.

I'll keep tinkering around, I assume there must be a setting somewhere not set, everything else is functional - I'll update this thread if I find something.

I was hoping I didn't have to do that, that's fine it wasn't as complicated eitherway. Thank you
