How to post Teams Channel post to Sharepoint as news

Hello,

Let's call my Sharepoint Team Sites A and B. We have a Teams Channel called ITAG that's using a connector to Site A. I want the messages from ITAG Channel to post as a news post in Sharepoint Site B. I tried to use power automate to do this but I keep it keeps on doing a timeout with "Bad Gateway".

Is this posisible? Attached is my flow. Should be pretty simple but I keep getting an error.
