How to call parent record in a nested form?

What I am trying to do: I have a AssignmentResource that is a nested resource of the ProjectResource . In my form I want to get the contacts of the project. What I did: Look at the code My issue/the error: I found a way to do it, but it gives me errors with PHPStan so I was wondering if there is a better / alternative way to do it. Code: 
final class AssignmentForm
{
    public static function configure(Schema $schema): Schema
    {
        // @phpstan-ignore-next-line
        $project = $schema->getLivewire()?->parentRecord;

        return $schema
            ->components([
                Select::make('contact_id')
                    ->label(__('Contact'))
                    ->relationship('project.relation.contacts', 'name',
                        modifyQueryUsing: function ($query) use ($project) {
                          if (empty($project)) {
                              $query->whereRaw('1 = 0'); // No project available, return empty result set
                              return;
                          }

                          $query->where('relation_id', $project->relation_id);
                    }),

                // ...
            ]);
    }
}
final class AssignmentForm
{
    public static function configure(Schema $schema): Schema
    {
        // @phpstan-ignore-next-line
        $project = $schema->getLivewire()?->parentRecord;

        return $schema
            ->components([
                Select::make('contact_id')
                    ->label(__('Contact'))
                    ->relationship('project.relation.contacts', 'name',
                        modifyQueryUsing: function ($query) use ($project) {
                          if (empty($project)) {
                              $query->whereRaw('1 = 0'); // No project available, return empty result set
                              return;
                          }

                          $query->where('relation_id', $project->relation_id);
                    }),

                // ...
            ]);
    }
}
Solution:
PHPStan will give errors in Laravel natively, ensure you are using Laravels IDE Helper too. But the parentRecord is the recommended approach....
