Pipedrive Trigger not working

Hey there, my Pipedrive trigger is not working, I receive this error message:

Problem running workflow
Bad request - please check your parameters

Show Details
Pipedrive Trigger: Validation failed

My n8n version is 1.83.2, all the other workflows seem to work fine, even the ones using other Pipedrive nodes.

Here’s my workflow (just a simple Pipedrive Trigger event on Deal Updated)

I think the issue is that you didn’t configure the webhook URL correctly

or maybe you are using test URL or Production URL ?!
