Getting the full error with post_p

[daleif]

This morning my webapps had an issue. We're using Mojolicious::Plugin::OAuth2 to auth users against Azure. Works perfectly fine, but not this time. Kept getting an unauthorized error. When I then messed with the code of Mojolicious::Plugin::OAuth2 and changed a post_p to a normal post and looked at the response, the content field actually fully explained the error.

My question is this. When we're using a promise chain like

$c->oauth2->get_token_p($provider_name => \%get_token)
  ->then( sub {...  })
  ->catch(
		sub ($err) {
			    die 'error: ' . $err;
		}
);

do we then have any chance of accessing the full error in the catch branch? Or are we doomed to only being able to access whatever is given to the reject part of the promise.

Here get_token_p ends by returning a post_p.

How about:

1. Use -async_await. For example: use Mojo::Base 'Mojolicious::Controller', -signatures, -async_await;
2. Mark your controller as async. For example: async sub my_sub ($self) {
3. Use try/catch. Consider:

my $result = eval { await $c->oauth2->get_token_p($provider_name => \%get_token) };
if (my $err = $@) {
  die 'error: ' . $err;
}

# check $result and do_something()
