Hi, i have a problem with n8n workflows. Automatically they work just fine. But when pressing Test workflow the following error emerges.
Problem running workflow
Invalid enum value. Expected ‘1’ | ‘2’, received ‘-1’

This error emerges on every workflow that i have on my n8n.

Did anyone had the same problem? What was the solution for you?
I would appreciate your answers&

I got the latest version of n8n.

Hi, i think it was a problem with cache on my laptop. Cause the self hosted n8n updated overnight. I cleared cache a it helped.
