Issue with Teams 'Add a User to Group Chat' API call?
I am getting a very strange error when trying to add a new user to an existing group chat using a GraphQL call. I have looked through the documentation, asked AI, and even contacted Microsoft support...

The request fails due to two issues: first, the @odata.type value was misspelled, causing Microsoft Graph to stop processing and return a misleading schema error. Second, an incorrect property was used instead of user@odata.bind. Correcting both issues resolves the problem. The proper request body must include the correct @odata.type, roles array, and the user@odata.bind reference to the target user.
{
"@odata.type": "#microsoft.graph.aadUserConversationMember",
"roles": [],
"user@odata.bind": "https://graph.microsoft.com/v1.0/users('USER_ID')"
}
