Problem with PHPUnit and encrypted casting fields while upgrading from Laravel 8 to Laravel 11

Already checked, yes it has one.

Is there any reason why it could fail ?

use RefreshDatabase;

protected function setUp(): void
{
    parent::setUp();
    
    $this->app->make(PermissionRegistrar::class)->forgetCachedPermissions();
}

public function test_user_without_permission_cannot_view_contacts_entreprise()
{
    $user = User::factory()->actif()->create();
    $entreprise = Entreprise::factory()->create();
    $contact = Contact::factory()->create(['entreprise_id' => $entreprise->id]);

    $response = $this->actingAs($user, 'web')->get("/entreprises/{$entreprise->id}/contacts");

    $response->assertForbidden();
}

It would be easier if you included the full error message, but it sounds like the column isn't encrypted on creation, and decryption then fails because it isn't valid ciphertext.

Show the factories and classes for those models that use encrypted fields.

I don't have any other error message than the one saying that the payload is invalid.

It was effectively the case.

In the factory, I just feed some fields, but not the encrypted fields.

I have added fake datas for the encrypted fields and it works.
