MS Teams App Updation Graph API gives error response even if app updation is successful

Question

Graph API endpoint to update an existing app gives response code as 400 instead of 201, but the actual updation happens successfully in the app catalog.

https://graph.microsoft.com/v1.0/appCatalogs/teamsApps/{app_catalog_id}/appDefinitions"

Response:

{
   "error":{
      "code":"BadRequest",
      "message":"Value cannot be null. (Parameter 'entity')",
      "innerError":{
         "date":"2024-12-09T13:20:03",
         "request-id":"e0744d75-91e0-43dc-aa32-21daf7c37916",
         "client-request-id":"e0744d75-91e0-43dc-aa32-21daf7c37916"
      }
   }
}

This happens for one app while for others, I am getting 201 response

Hi Neelu George,

Thanks for reaching out to Microsoft!

As mentioned here in the document: it is recommended to use the ID returned from the List published apps call to reference the app you'd like to update.

In the request body include a Teams zip manifest payload.

When you publish your app to the Microsoft Teams Store, ensure your app manifest references to the latest app manifest schema and entity values are not empty.

Once the Update an application previously published to the Microsoft Teams app catalog is successful results in 204 No Content

Hope this helps.
