Graph API: PUT / beta / groups / <groupId> / command Authentication failed

Question

Problem

PUT request /beta/groups/<groupId>/team fails:

 { "error": { "code": "AuthenticationError", "message": "Error authenticating with resource.", "innerError": { "request-id": "e4385864-85e4-4fa6-8878-458988c584e4", "date": "2017-11-10T10:29:39" } } } 

A bearer token is provided that was generated using delegate rights on Group.ReadWrite.All .

The endpoint is documented here .

Things I've found so far

It seems that this is something related to the resources of the teams. The following queries do not work:

• PUT /beta/group/<groupId>/team
• GET /beta/me/joinedTeams

Both do not work with AuthenticationError .

Update

/beta/group/<groupId>/team now works.

Answer 1

There was a problem when we got an access token for graph.microsoft.com/ with a trailing slash. This has been fixed, and now you should be able to call / beta / group // team using the token obtained using the slash.

Note. Conducting this as an answer so that other participants cannot go through all the comments.

Answer 2

For those who are still facing this issue in 2018: Whiteid said they have installed a generation of tokens with a slash, which is partly true. End slash token generation works for successful requests, but not for failed requests.

'/ beta / me / joinTeams' still returns an AuthenticationError for us. Only when we removed the trailing slash from the token generation did we get a more descriptive error message stating that our test user did not have a team license.

Everything worked fine by providing our test user with the correct license.
