Malformed JSON response when GETting /me/memberOf (Microsoft Graph) - json

Question

I'm trying to set up a sign-on process for an internal company web app using the Azure AD and Microsoft Graph. I want to manage security groups in the AD, so when a user signs in via OAuth, I'm doing a GET request to https://graph.microsoft.com/v1.0/me/memberOf to see which groups the signed-in user is in. The user has the appropriate scopes to see this information, and it works in the Graph Explorer, but when I make the call in my PHP application, I get a malformed JSON response:
{
"#odata.context": "https://graph.microsoft.com/v1.0/$metadata#directoryObjects",
"value": [{
"#odata.type": "#microsoft.graph.group",
"objectType": "Group",
"objectId": "blahblah2",
"deletionTimestamp": null,
"description": "Users who have access to my web app's administration",
"dirSyncEnabled": null,
"displayName": "Web App Administrators",
"lastDirSyncTime": null,
"mail": null,
"mailNickname": "blahblah2",
"mailEnabled": false,
"onPremisesSecurityIdentifier": null {
"error": {
"code": "InternalServerError",
"message": "Unsupported extension property type.",
"innerError": {
"request-id": "blahblah3",
"date": "2016-02-29T09:42:18"
}
}
}
...and that's all I get!
The documentation at https://msdn.microsoft.com/en-us/library/azure/ad/graph/api/entity-and-complex-type-reference#GroupEntity says that this onPremisesSecurityIdentifier field is something to do with on-premesis sync, but i've never used that.

Your request had api-version query parameter appended (i.e. /v1.0/me/memberOf?api-version=1.6). Please remove that query parameter. Microsoft Graph identifies the API version by the first segment in the URL path, e.g. https://graph.microsoft.com/v1.0/me/memberOf or https://graph.microsoft.com/beta/me/memberOf
