Hi @LALITAMITTAL18,

I'll help to track this issue and figure out why the Error occurs. By the way, could you share which Teams Template you created?

Got it. I'll have a try for this template. Thanks.

Hi @LALITAMITTAL18,

It seems your UPN is not configured. To verify this, you could try:

1. Retrieve UPN locally by following this sample
2. Go to the Microsoft Admin Center to check if necessary configration is set.

The best solution we recommended is to register a M365 test account and use the new account to develop and test teams app locally.

Yes it worked. There was some issue with logged in user. I have to sign out and sign in again using embedded browser.

Hi @LALITAMITTAL18, Thanks for you feedback and glad to see the solution works for you.

For the logging issue, It seems out the scope of "Preparing Teams App Dependencies". Could you file another issue for that? And I'll close this one then.

Thanks a lot.
