Below I present evidence of the process carried out.
- I create a Teams project for Tab
- Ejecuto Prepare Teams Apps Dependencies
- I select a 365 Work Account
- Prepare Teams Apps Dependencies is executed
and as shown in the image it has an error.
Below I present development environment
As I mentioned before, I have used the same Office 365 work account in Visual Studio Code and Teams Toolkit and it has been configured and run correctly. I mention this to rule out setting up an Office 365 account.
