Unable to assign owners to private channels with Graph API

Question

Hi,

I've previously created an issue on GitHub because I was unable to assign owners to a private channel. I encountered the same error response when I executed the request directly in the Graph Explorer without going through the SDK (tried both v1.0 and beta routes):

• URL: https://graph.microsoft.com/{version}/teams/{team-id}/channels/{channel-id}/members/microsoft.graph.add
• Verb: POST
• Request's payload: same as this example
• Response
  • Code: UnknownError
  • Message: 404 page not found

The user who executes the request has the appropriate delegated permission required to manage channel membership, as dictated here.

Note that I mitigated this problem by instead defining the channel membership when I created the channel rather than post creation, but I thought it would be good to raise the issue so that it can be resolved for good.

Hi Félix Pelletier,

Thanks for posting in the Q&A forum. We need a bit more details on the error code and message that you are seeing.

We recommend to open a case with Azure supportso that this can be addressed directly to our support staff.
