Cannot create an alert with error Request failed with status code 500

Hi v-kpoloju-msft , Thank you for the solutions you provided. Unfortunately, none of them worked. I tried sending an email, which did go through, but team app messages still aren't functioning. I found an app called Fabric Activator that needs to be added to Teams, and I'm currently seeking approval for it. Please let me know if you think I'm not on the right track with this solution or if you would like me to try something else.
