Can't add users to groups

[johnf]

Describe the bug

I'm trying to add a user to a group as follows

export const addUserToGroup = async (userId: string, groupId: string) => {
  try {
    await client()
      .groups.byGroupId(groupId)
      .members.ref.post({
        odataId: `https://graph.microsoft.com/v1.0/directoryObjects/${userId}`,
      });
    return true;
  } catch (error) {
    console.error('Error adding user to group:', error);
    return false;
  }

I get the following error

Error adding user to group: {
  errorEscaped: {
    code: 'Request_BadRequest',
    message: "Unrecognized query argument specified: '@id'.",
    innerError: {
      date: 2025-11-09T12:25:07.000Z,
      requestId: 'xxx',
      clientRequestId: 'xxx'
    }
  },
  message: "Unrecognized query argument specified: '@id'.",
  responseStatusCode: 400,
  responseHeaders: {
    'client-request-id': [ 'xxx' ],
    'content-encoding': [ 'gzip' ],
    'content-type': [ 'application/json' ],
    date: [ 'Sun', ' 09 Nov 2025 23:25:07 GMT' ],
    'request-id': [ 'xxx' ],
    'strict-transport-security': [ 'max-age=31536000' ],
    'transfer-encoding': [ 'chunked' ],
    vary: [ 'Accept-Encoding' ],
    'x-ms-ags-diagnostic': [
      '{"ServerInfo":{"DataCenter":"Australia East"',
      '"Slice":"E"',
      '"Ring":"5"',
      '"ScaleUnit":"000"',
      '"RoleInstance":"xxx"}}'
    ]
  }
}

Expected behavior

The user is added to the group

How to reproduce

Other information

I'm happy to generate a PR with the above if the fix is sensible.

I'm also new to the API so it's possible my code is not taking the right approach

Thanks for raising this @johnf

Raising a PR to change that wouldn't really help as that code is generated from the specification that we have for Microsoft Graph using kiota

The invalid URI Template was introduced in bf57e0d

Tracing it back, we use a single UrlTemplate per request builder that represents all of the requests for a given path segment. The changes made in microsoft/kiota#3989 made the required @id parameter for the delete a required part for all the requests and broke the POST operation here.

I'm transferring this to the kiota repo as that's where the fix needs to happen.

This will be impacting all languages :|

Ahh shoot, can't do a cross org transfer... Opening an issue there...

@gavinbarron Did you end up opening the other issue? I had a quick look but couldn't find it.
