PKCE token request errors not handled and request is not shown.

[mricherzhagen]

There is no error handling for the PKCE token request, and the request that is attempted is also not shown in the UI.

The PKCE token request can fail, for example, if there is no CORS-setting on the server for oauthdebugger.com.

The request should be shown, and the errors should be caught and displayed.

Nevertheless, very useful tool. A little bit surprised it requires a server component, though.

This is a good suggestion, thanks!

I tried to eliminate this, but a server is required for handling POST-based redirect flows.
