Question

Teams Tab App - getting "Something went wrong" error when installing

Anonymous

We are developing a tab app for MS Teams. As part of our testing we created a sandbox instance of Teams and tried uploading the app and adding it to a Team and to a Chat. When we try to add the tab we get this error in the console:

"CDL: {errorCode:Error,requestId:m-29,component:RequestHandler,requestWindowId:main,operationType:mutation,operationName:installApp,message:error while processing m-29: {name:Error,message:Unexpected error value: App definition not found,stack:[]} (reason: undefined),hostRendererId:our-id-goes-here}"

What is the App definition?

As far as I know all the permissions are correct and I ran the manifest through the MS validation service. Everything came back as correct.

@Josh Brown - Thanks for reporting your issue.
If Possible, could you please share the manifest so that we can try it from our end?

@Josh Brown-We have tried the scenario but not able to repro the issue as it is working fine from our end.
Microsoft Teams Version 1.6.00.7879 (64-bit).
We are checking internally, and we will update you once we get any update.

It magically works now all of a sudden. We did not make any changes. I can only guess that it needed more time to propagate the updated version of the app.
