Solved - It was not executing any HTML request because I was not sending any item as an input. Thanks.

nodes are executed ONLY if an item input is passed, I was overlooking such a basic building block of n8n.

Hello Jeremet!

I have the same issue. I see that you were able to solve it but I don’t understand how you solved it exactly. Could you help me out by elaborating on your fix?

Thanks for your time.
