Answer 1

The problem is because some of $request properties are arrays. You can't store an array in integer, string etc columns. If you want to store them as arrays, you can serialize them:

$customer->service_id = json_encode(service_id);

And store in text or json columns:

$table->json('service_id');
$table->text('service_id');
