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