Microsoft Flow: @mention action not working for Teams reply

Hi harveer singh,

thanks for your detailed explanation!

I rebuilt my flow with the exact same objects and values to your example but still I'm getting these nasty errors. I even tried other channels and other users with which I built the flow, still no luck.

Following is a screenshot of my current flow, though in german but should be same elements:

Maybe you notice something.

The errors occur as soon as I add the  mention Token action to the flow, first for the condition and as as soon as I add the last reply to message action, the 2nd error is popping up^^

Best Regards
