Describe the bug / error

Hello everyone, i currently have a spfx app which worked for the last 1.5 Years now. I updated the app and now im unable to add the application to teams anymore, without any (informational) error. So i tried to create a new app and can reproduce this behaviour with it.

Steps to reproduce

• yo @microsoft/sharepoint
  • Which client-site component: WebPart
  • Template: Minimal
• Execute inside folder: gulp clean && gulp bundle && gulp package-solution --production
• Take the sppkg file from /sharepoint/solution folder and upload it in .sharepoint.com/sites/appcatalog/_layouts/15/tenantAppCatalog.aspx/manageApps
• During upload it will ask to add it to teams, check it
• After upload, go to teams in an existing channel, add a new tab and search for the Project (name given in step 1)
• it will fail

I opened developer console and saw an request which fails everytime i try to add the app. It calls .sharepoint.com/_api/web/hostedapps/add which results in 500 Internal Server Error with this body.

{
    "error": {
        "code": "-2146232832, Microsoft.SharePoint.SPException",
        "message": "hostedAppConfigsList null"
    }
}

Any help would be appreciated!

Expected behavior

The app should be able to add as Teams Tab, as before, or if the error is right - it should display a meaningful message

hi @tboehm-yourBytes , did you try adding TeamsTab to supported hosts in the manifest of your SPFx app? "supportedHosts": ["SharePointWebPart", "TeamsTab"],

Please check if this doc helps - https://learn.microsoft.com/en-us/sharepoint/dev/spfx/integrate-with-teams-introduction

I have the same behavior

code: "-2146232832, Microsoft.SharePoint.SPException" message: "hostedAppConfigsList null"

if I add a custom app to a new Team the request goes to the root an get this error https://xxx.sharepoint.com/_api/web/hostedapps/add

When I first open the Files Tab and add as second step the custom app the process work

we have also faced the same problem when we try to add SPFX solution app as a tab in the new microsft teams, but it works fine with the classic teams, we get this error message { "error": { "code": "-2146232832, Microsoft.SharePoint.SPException", "message": "hostedAppConfigsList null" } }
