Getting "InvalidAuthenticationToken" error code and "Access token is empty." while trying to login to upload to OneDrive

Question

var scopes= "files.readwrite files.readwrite.All User.Read offline_access";

var url = 'https://login.microsoftonline.com/common/oauth2/v2.0/authorize?' +

		   	'client_id=xxxxxxxxxxxxxx'+	

			'&scope=' + scopes +	

			'&state=xxxxxxxx' +	

			'&response_type=token' +	

			'&redirect_uri='+ redirect_uri;	

Is there something I should do or am I doing something wrong ? It is working fot me but it is not working for one of my clients.
