This repository is meant to be used as an example for the issue phpstan/phpstan#6585 It uses the predefined github action extdn/github-actions-m2/magento-phpstan to run phpstan on push and pull request events. To reproduce the issue, simply create a pull request with an empty file or push something unrelated. This will trigger the phpstan action and you will (in most of the cases) get the following error:

 ------ --------------------------------------------------------------------- 
  Line   Model/FailingFunction.php                                            
 ------ --------------------------------------------------------------------- 
  11     Method CustomGento\Phpstan\Model\FailingFunction::failingFunction()  
         should return array but return statement is missing.                 
 ------ --------------------------------------------------------------------- 

As you can clearly see in the file, this is obiously not the case.

    public function failingFunction(): array
    {
        return [];
    }

I would expect a green checkmark, since the code is valid and the phpstan check should pass.
