Bug introduced by
The method handlePush() does not exist on null. ( Ignorable by Annotation )

If this is a false-positive, you can also ignore this issue in your code via the ignore-call  annotation

37
        return $this->stack->/** @scrutinizer ignore-call */ handlePush($request);

This check looks for calls to methods that do not seem to exist on a given type. It looks for the method on the type itself as well as in inherited classes or implemented interfaces.

This is most likely a typographical error or the method has been renamed.
