I am also facing the same issue, same errors. We are running late for delivery because the deployment cannot be done.
Thanks in advance

Hi @ShubhamSengar29, @ryotien111100, @IAM5K, sorry for the late reply. The issue occurs because you created a Teams app (T1) in account A, and then switched to another account (B). When you run the same project again, it tries to create a Teams app using T1 in account B, but the app ID cannot be duplicated, so it fails.

To resolve this, after switching accounts, please modify the TEAMS_APP_ID value in env/.env.local or env/.env.dev to avoid duplication. Alternatively, you can delete the value of TEAMS_APP_ID, and Teams Toolkit will automatically assign a unique ID to create a new Teams app.

Hi @huimiu, I am trying with new app also and it's producing the same error and one of my colleague also tried but he is facing same issue. I tried clearing the value in env.local then this issue comes and if i try with same id then i get "something went wrong" error popup.

Hi @ShubhamSengar29, would you mind share what app you created and the subsequent detailed steps until you encountered the error? I'll try to repro this issue to see what's the cause is.

[ShubhamSengar29]

Hi @huimiu, I selected the option created new app from teams toolkit then selected the tab as application i want to create then selected React with fluentUI then language as Typescript then the path where i want to save application then name of application.
the new app will open in new window and after either goto debug section in vs code and click on play button or use F5 to start debugging.
when debugging starts and it comes to create teams app id task it fails with the error failed to create app id

[huimiu]

@ShubhamSengar29 thanks for your detailed explanation. I'll try to reproduce the issue, and I'll let you know if there are any updates.

[ShubhamSengar29]

Please help with this issue because the issue is still same.

[MrKSchmitz]

Should be easy to reproduce, since all you have to do is attempt to create a new app using the VS Code Teams toolkit.
This will fail with the same error.

Apps fail when attempting to launch debugger.
Fails at "teamsApp/create".

This seems to happen fairly often (plenty of duplicates):

@anchenyi
Tested the pre-release and can confirm this seems to provision, deploy & debug as expected. Thanks.

As the issue is resolved close it now.
