Fix your Accessors and Mutators like this in Your model. these functions are case sensitive

public function getPropertyTypeAttribute($value)
{
    return json_decode($value);
}

public function setPropertyTypeAttribute($value)
{
    $this->attributes['property_type'] = json_encode($value);
}

if you're using Laravel 8.77 or later also you can use them like below.

use Illuminate\Database\Eloquent\Casts\Attribute;

protected function propertyType(): Attribute
{
    return new Attribute(
        fn($value) => json_decode($value),
        fn($value) => json_encode($value)
    );
}

the first parameter is the getter and the second one is the setter.

Use casts in laravel. casts in laravel

Add this to the Project model:

protected $casts = [
        'property_type' => 'array',
    ];
