Create Kernel.stubphp

[enumag]

class Kernel extends BaseKernel
{
    use MicroKernelTrait;

    protected function configureContainer(ContainerConfigurator $container): void
    {
        $container->import('../config/{packages}/*.yaml');
        $container->import('../config/{packages}/' . $this->environment . '/*.yaml');
		// ...
    }
}

Psalm:

ERROR: MixedOperand
at /app/src/Kernel.php:17:54
Right operand cannot be mixed (see https://psalm.dev/059)
        $container->import('../config/{packages}/' . $this->environment . '/*.yaml');

@seferov fixed and added a test

@enumag thank you!

This stub introduces a PropertyNotSetInConstructor when using for example:

class AppKernel extends Kernel
{
    use MicroKernelTrait;

    public function __construct()
    {
        parent::__construct('test', true);
    }
}

due to vimeo/psalm#2319 I guess, I don't know if there is a workaround for this 😕

The original issue maybe can be solved by using $this->getEnvironment()
