Since yesterday I get error messages while trying to call a Teams webhook of my channels.
"Webhook message delivery failed with error: Microsoft Teams endpoint returned HTTP error 500 with ContextId tcid=105260188274304390,server=EAP010211239200.." Is the answer I get by running my demo scripts that worked now for a few months. I get this now on every webhook I configured at this tenant. All of them worked by Friday but are broken since at least Saturday evening UTC.
At first, I thought maybe something gone wrong with that tenant. Today I created a new Team in a different tenant in the web interface. I tried to create a webhook and boom:
So at least 2 tenants with error 500 while dealing with connectors in Teams. Anyone else getting these kinds of errors at the moment?
