@BookerE1 I found it!. There was already another thread related to this problem and someone else helped me find the solution (Problem was the pool that I was using for the pipeline)

This is the link to the other thread: https://community.databricks.com/t5/get-started-discussions/getting-html-sign-i-page-as-api-response...

Thanks for all your help and goodwill. Have a good one!
