It seems like $path defined by $this->getFilename($name) on line 54 can also be of type false; however, Twig\Source::__construct() does only seem to accept string, did you maybe forget to handle an error condition?

The variable $plugin does not exist. Did you forget to declare it?

The call to Plugin::loaded() has too many arguments starting with $plugin.
