Answer 1

Most probably you have a duplicate setting for the controller factory in the module.config.php. Check:
'controllers' => [
'factories' => [
Controller\PostController::class => InvokableFactory::class,
...
],
],
Remove line:
Controller\PostController::class => InvokableFactory::class,
so that the factory method in your Module.php is used.
