Hi Sayali-MSFT , thanks for your reply!

you mentioned "Check if you had created policy for that tenant user"--Could I know what kind of policy, actually I have no extra policy set for the tenant user during configure the bot except the online meeting policy mentioned in https://docs.microsoft.com/en-us/microsoftteams/platform/sbs-calling-and-meeting?tutorial-step=2

I can see
POST /api/messages 502 Bad Gateway OPTIONS /api/messages 502 Bad Gateway
