Hello Danielle,
seems I found a bug in 3.0.5 (maybe earlier).
I have a webhook setup on submission of a form. If I downgrade to 2.2.7, everything seems to work fine.
On 3.0.5 I get an error when submitting the form.
Screenshot from the console is here:

Thanks in advance
Hey 
I cannot reproduce this. Webhooks are working well here. Could you check your PHP Error Logs for the exact error?
Thanks very much!
Hello Daniele,
the error is:
Ok, I think I have found the culprit @Daniele . It was a field that had the same id as a key within the webhook and it caused a conflict. Probably in earlier versions, this was handled a bit differently. Anyways, it is now solved.
