Documentation Bug introduced by
The property $token was declared of type boolean, but $token is of type string. Maybe add a type cast?

This check looks for assignments to scalar types that may be of the wrong type.

To ensure the code behaves as expected, it may be a good idea to add an explicit type cast.
