This happens when your webhook secret is not configured properly and therefore is not being passed to the plugin.

Maybe you have limited the secret to specific events which doesn't work for this case?

[gtaylor]

This lack of error message confused us at the time as well. May be worth a separate issue to improve the feedback.

Thanks @tboerger event pull_request got missed out for the secret. I've added it using the update cli command of drone secret.

[tboerger]

@gtaylor would make sense to add an empty check for this variable, than it gets more obvious where it comes from.

I am closing the issue
