I'm using Next.js with Typescript and when I use return of the response methods (ex. res.status) I get an error: API handler should not return a value, received object.
However, if I remove the return statements and just call res.status directly Typescript starts complaining about undefined values. Looking in the docs, it doesn't show an example using a return statement so obviously this is the intended way, what am I missing?
