Google Sheets Webhook is not working

Hi, I have developed an automation that grabs information from Google Sheets and search and update a Notion item. I used to have it with Watch new rows but I wanted to change it for Watch changes. The problem I encounter is that is not working properly my webhook. I have tried many things such as creating a new one but it doesnt work and return 0 output, can someone help me? I have also read that we can use App Scripts, someone has the script for it?

I have read that if is a Sheet is connect to a Form, there could be problems. My file is connected to a form, but in another sheet is ok?
