add-app-dialog-v3-add-button: App sideloaded for personal scope failed [object Object]

[firstteam]

Hello,

I am a just beginner of Teams app developing. 

I just followed this exactly same step..

https://docs.microsoft.com/en-us/microsoftteams/platform/build-your-first-app/build-and-run?tabs=do-...

I clicked "Add" button..then it shows "Something went wrong".... I looked at the console of Visual Studio Code...

App sideloaded for personal scope failed [object Object]

statics.teams.cdn.office.net/hashed/0.2-angular-jquery.min-eee9041.js:114

{message: '', status: 400, errorCode: 'CreateUserAppDefinitionFailed'} undefined

arg0:{message: '', status: 400, errorCode: 'CreateUserAppDefinitionFailed'..

I researched a bit..but I couldn't find many..one thing I found was that someone mentioned that could be manifest error..but I haven't changed it...All I did was just try to distribute to see how it is going to work..

When I just invoked in the browse, "https://localhost:3000/tab",  I see this default message..

" Hello World! Congratulations ! This is the tab you made :-)"

Any clues? What should I do to add this "Hello World" so I can see this actually in the MS Team then?

Thanks,

Hi @firstteam, could you please try uninstall and install the app from you app studio.

[#3]

@Jagadeesh-MSFT,
What do you mean?. You mean uninstall Microsoft Team Toolkit and install it again? Ok.. I did..but still same thing.

[#4]

Or you mean "Install" Button in the App Studio..Actually, I didn't install this one..because when I clicked "Install" button, nothing happened...seems like didn't do any action...so I did F5(start debugging) from the visual studio code to test....Once I did that...I see that "Add" button on the pop window..then clicked it..then I saw "Something went wrong"..

[#5]

Ok.. never mind about this issue. Somehow it started working...I saw my HelloWorld in the Team app. However, the strange thing is that......Here is what is happening... I was able to test...then I closed my Visual Studio Code...then opened the same Hello World workspace...then I tried to test again..now it says that "App not found, Please verify the app and it's access permissions."... Strange...is there something I would need to do every time before I start debugging? What is it then? Now why am I seeing this message, "App not found, Please verify the app and it's access permissions." ???

Now I just tried this..

https://docs.microsoft.com/en-us/microsoftteams/platform/build-your-first-app/build-channel-tab

Then....now I see this message..

"App not found, Please verify the app and it's access permissions."

BTW, I realized this development environment is so acting strangely. I have no idea what causes this.. I looked at the browser console..

https://teams.microsoft.com/api/appstudio/appdefinitions/42c029d1-8f58-4d64-9cde-e18a2f942bf3/manife... Get 404..

It looks like somehow my manifest hasn't been uploaded to the server??..then why is that? Is there anything I would need to do other than clicking "start debugging"? BTW, still,
Install button under Test and distribute in App Studio ... doing nothing...it didn't respond any when I clicked "Install" button.. so only way I could see the action is by "Start Debugging" from Visual Studio Code......

[#7]

Ok..I think I figured this out. I think I MUST download, and then upload that zip in order to start testing. HOWEVER, this is VERY inconvenient. Is there any way I could upload it automatically somehow by pressing F5(Start debugging)???? ..BTW, also my ultimate question again is that why "Install" button is doing nothing?????????
