OAuth gateway does not show error messages

[danpalmer]

I have deployed an OAuth application that uses https://auth.monzo.com/, but I forgot to add the production redirect URL. This means that login does not work.

When I click the "Submit" button, nothing happens.

Using the web inspector I can see that the button is initiating a web request which is receiving a 400 status code with the payload:

{
    "code": "bad_request.bad_param.redirect_uri",
    "message": "Mismatched redirect_uri"
}

This makes sense given the error I made, but no error message was shown. It would be great to at least have a generic error message, the literal message provided here might be even better (if not understandable by most).

Just came across the same issue, but looking at the creation date of your ticket I doubt that anyone at Monzo will take care of it.
