"Error in workflow" in HTTP Request

I’m following the Workflow 2 Level 2 course but i’m stuck on an error in Http Request Node.
It replies “Error in workflow”.
I created it by duplicating a previous node that was OK, but at the moment I set the unique ID value, I get this error.
Can you help me ?

Hey @williamdevelis,

Welcome to the community :cake:

Can you share the workflow you are using and the n8n version?
