Getting error when accessing Microsoft Teams channel messages via Microsoft Graph API: Proxy_InternalServerError

Question

When getting Teams channel messages via delegated permissions (user is a member of the team):

https://graph.microsoft.com/beta/teams/{team_id}/channels/{channel_id}/messages/

Getting error:

{
  "error": {
  "code": "Proxy_InternalServerError",
  "message": "Failure in forwarding request.",
  "innerError": {
    "request-id": "511b812c-df43-402b-b9dd-34ca1c1bd397",
    "date": "2019-02-01T14:22:50"
  }
}

Tested with Graph Explorer and code.

Does it work for anybody?

Check your channel id. probably colon is missing in the Channel ID or formation is not correct. It should be in the below format - 20:[email protected]
