Seeing some odd behavior with creation and enabling Zaps. I have created a new Zap (Pipedrive + Slack) that is published and enabled and triggering just fine. I then duplicated that and changed a few fields in the trigger (different Pipedrive pipeline stage as the trigger), and that new Zap is published just fine, but will not enable providing the following error (only at the Zaps page not on the Zap itself):
Error turning Zap on: No valid draft found for Zap
Creating the second Zap itself from scratch seems to have the same result as duplication also. Even editing and saving another draft with a draft message yields the same result.
