Unable to handoff user to live agent from Microsoft Health Bot Service to Microsoft Teams

Hi,

I had configured health bot according to these link https://docs.microsoft.com/en-us/healthbot/handoff-teams and i am successfully able to login agent on Microsoft Teams. Imported triage template from Scenarios -> Manage -> Open scenarios template catalog. I didn't modified any thing from the scenario and Enabled Human Handoff but as i type agent and it replies Sorry, it seems I can’t answer this and at the end i get Handoff scenario error. For more reference find attached image of Human Handoff window.

Whenever I send list in Microsoft Teams I get user is in conversation with bot, so how to send user in waiting queue. I have also reviewed these links many times https://docs.microsoft.com/en-us/healthbot/handoff https://docs.microsoft.com/en-us/healthbot/handoff-teams I don't know where i am getting wrong.

Any response from your side with be appreciated.
