Why does Eloquent (in Laravel) translate my varchar uuid primary key to an integer leading to errors?

Question

Following the question last night , I had a good night of sleep and “was discovered” that this was due to an automatic cast / type conversion or something else.

To arrange summer:

• Models use uuidas primary key
• They get them using triggerthe insert from mySQL
• To get the uuid generated by the database environment, I call $model_object->fresh(); fresh()
• This works when retrieving the whole object, but not when selecting only the attribute

Model

<?php namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Address extends Model {

    protected $table = 'Addresses';
    protected $fillable = ['uuid', 'zipCode', 'houseNumber'];
    protected $primaryKey = 'uuid';
    //public $incrementing = false;
}

Controller (where it is mounted)

public function store(Request $request) {
    $input = $request->all();
    $address = Address::create($input);
    var_dump($address); exit;

// result (as expected)

    $address = $address->fresh();
    var_dump($address); exit;

// result (as expected)

var_dump($address->uuid); exit;//result (wow): int(0)
}

  'id' => 'string'
