Hello World sample: "Something went wrong" when installing/testing - json

Question

I tried to get the example from https://learn.microsoft.com/en-us/microsoftteams/platform/get-started/get-started-dotnet to run.
I successfully built and published (on Azure) the webapp.
Then I tried
- manually editing the json file in the visual studio solution similarly to what the docs said, and then import the resulting zip in App Studio
- adding the App directly in App Studio through the manifest editor (this works, but it fails when installing/testing it)
Both give me an error without any more info "something went wrong".
Any way to actually figure out what I did wrong (if anything)?
Either way, maybe you guys can figure it out from the json file's contents:

Any suggestions?

Answer 1

There is a whitespace in your app Id in shared manifes:
"id": " 1CC58D17-1E95-443C-958F-E1F14D4CA3B4"
Could you please remove it and try and let us know if it works? Also you can remove bots and composeExtensions section if you want.

Answer 2

I can't comment yet (not enough reputation points) but could you go through the instructions again?
I believe something went wrong with either the GUID, or one of the URL's. The instructions also advise to use ngrok, which is usefull for debugging.
If you can't find a clear error message, i advise you follow those instructions.
