Getting "Access token is empty" response with Microsoft Business Account

[harisiddigital]

Hi.
I created an app on azure and using its Client ID and Client secret I am able to authenticate and everything works as expected but when I try it with a Microsoft Business Account I get "Access Token is Empty error".
Here is my configuration, I used microsoft online urls for auth and token:

`
/**
* Default scopes
*
* @var array

 */
public $defaultScopes = 'openid profile email User.Read.All';

/**

 * Base url for authorization.
 *
 * @var string
 */
protected $urlAuthorize = 'https://login.microsoftonline.com/common/oauth2/v2.0/authorize';

/**
 * Base url for access token.
 *
 * @var string
 */
protected $urlAccessToken = 'https://login.microsoftonline.com/common/oauth2/v2.0/token';

/**
 * Base url for resource owner.
 *
 * @var string
 */
protected $urlResourceOwnerDetails = 'https://graph.microsoft.com/v1.0/me';`



Moreover, When I debug the app, I get the token in `$token` but for some reason it doesn't get appended to ResourceOwner detail call and that call returns Access token is empty.

Anyone else faced the same issue?

I am experiencing the same issue. I do receive a token but when appending the ResourceOwner details i will get a Access Token is empty...

I’m a bit late, but for anyone else encountering this issue: the new Microsoft Graph resource URL https://graph.microsoft.com/v1.0/me use a new mechanism. According to the official documentation (see Microsoft Graph documentation), you should use Bearer authentication (i.e., the Authorization: Bearer {token} header). However, this library is sending the token as a GET parameter (access_token), which is not supported and generate the error: Access Token is Empty error
