Configuring Teams app failed

[Diman96]

When I try to create an application like it says in the tutorial (https://docs.microsoft.com/en/microsoftteams/platform/sbs-gs-blazorupdate?tabs=vs). In step 1 Select Project > Teams Toolkit > Configure Your Microsoft Teams.(https://docs.microsoft.com/en-us/microsoftteams/platform/sbs-gs-blazorupdate?tabs=vs&tutorial-step=3)

I get an error like this

And output

Any updates?

[JerryYangKai]

@Diman96 Thanks for reporting this issue, also this log is very helpful, I will take a look at it with my teammates.

[JerryYangKai]

@Diman96 Is this still blocking your local debug? Could you please log out and re-signin your account and try again.

[Diman96]

@JerryYangKai I logged out of my VS account and logged back in. This did not help, the error is the same. I also logged out of my account and the teams toolkit window prompted me to log in to my account and it didn't help the error remained the same.

The output started to look like this:

Add @xiaolang124 , could you please help figuring out whether the log in is blocking, thanks.

[xiaolang124]

Sorry for you inconvenience. What account do you use for Configurate Teams app, is it personal account? If yes, please change it to a work account, and try again. If not, can you try to create a free Teams developer tenant and try again? We will investigate more on this problem.

[Diman96]

@xiaolang124
Before that, I used my work account.

When I created free Teams developer tenant and log in with this account in Visual Studio. I try Configure Microsoft Teams app again, my output starts look like this:

It may be caused by our toolkit encoding compatibility issue. What language do you use for your system and what encode type do you normally use? Or what is your VS default encode type?

[Diman96]

@xiaolang124 Visual Studio in english, OS in russian, but I changed it to english and it did not help, connected such language packs for keyboard as russian, ukrainian and english.

What exactly do you mean by the "encode type"? In Windows should use the standard encoding utf-16 if I'm not mistaken, but where to see it and check, I don't know.

[xiaolang124]

I have reproduced this problem by this step. It may be the same reason that caused the issue. I created an account with the name João, and I tried to log in and Configure Microsoft Teams app. Then the toolkit will pop up this error.
For the short term, you can create an account in your free Teams developer tenant with pure letters and try again.
For the long term, we will fix this problem and support this scenario.
Thanks for reporting this.

I experience same issue with the latest Visual Studio Community (17.11.0. Preview 1.1).
Cannot debug in Visual Studio anymore, and for that matter, cannot even start my bot locally.
Ant solution for this?
