Question

Unit testing

Tell me why the error when testing Failed asserting that an array has the key 'id' ?

public function test_qr_code_customer()
{
    $token = 'v4jdlUW5W370VchqlSIDzL5LHjqxXv4jgo37dTP2';

    $response = $this->withHeaders([
        'Authorization' => 'Bearer ' . $token,
    ])->get('/api/qr-code/customer');

    $response
        ->assertOk()
        ->assertJsonStructure([
            'ok',
            'data' => [
                'user' => [
                    'id',
                    'code'
                ]
            ]
        ])
    ;
}
