Error handling server/client ?

[michaelsauter]

First, thanks for this tool! I really like it so far.

I'm wondering a bit though how errors are supposed to be handled? Maybe I'm missing something, but what I'm seeing is this:

If I return a non-nil error from one of the service endpoints, a 500 is returned to the client with the body being the error message (https://github.com/pacedotdev/oto/blob/master/otohttp/templates/server.go.plush#L46-L47). On the client side, the response is assumed to be JSON though (https://github.com/pacedotdev/oto/blob/master/otohttp/templates/client.ts.plush#L38), which leads to a JS error like SyntaxError: Unexpected token c in JSON at position 0. So out-of-the-box that seems a bit broken ... and I'm a bit confused why the "service endpoint error" is not simply handled with s.server.OnErr(w, r, err), like in the other error cases? Would be great if you could shed some light on this!

Hey @michaelsauter thanks for raising this. You're right, we will change that to just call OnErr.

@michaelsauter that's fixed now. Remember, you are free to copy and make any changes you like to the templates. This is the easiest way to customise Oto.

@matryer Thanks! Yes I changed the template to use OnErr, but I wasn't sure if there was a specific reason NOT to do this ... thanks for clarifying.
