empty secret would just show "bad credentials"

[chmouel]

I have setup a incoming webhook but i guess that's going to be the same issues on github-webhook or any other webhook based provider.

The secret was here but the key to the secret different than the default one. So it came back empty. The PAC controller only shows "Bad Credentials" when it should error out to something like "No secrets has been found" or "Secrets is empty" (if there but empty)
