"Trying to get property of non-object" when executing test of a JSON request on Symfony 4.1

I'm trying to write a test case to test my operation to persist data into the database using Symfony 4.1. The operation is already working and it is the following:

public function storeAction(Request $request)
{
    $data = json_decode($request->getContent());

    try {
        $entityManager = $this->getDoctrine()->getManager();

        $createdAt = \DateTime::createFromFormat("Y-m-d H:i:s", $data->createdAt);
        $concludedAt = \DateTime::createFromFormat("Y-m-d H:i:s", $data->concludedAt);

        $task = new Task();
        $task->setDescription($data->description);
        $task->setCreatedAt($createdAt);
        $task->setConcludedAt($concludedAt);

        $entityManager->persist($task);
        $entityManager->flush();


        return $this->json([
            "message" => "Task created",
            "status" => 200
        ]);
    } catch (\Exception $e) {
        return $this->json([
            "error" => [
                "code" => 500,
                "message" => $e->getMessage(),
                "file" => $e->getFile()
            ]
        ]);
    }
}

Using Insonmnia REST with it sending a JSON works. But the test will show me

Trying to get property 'createdAt' of non-object

pointing to my controller class. This is the test:

public function testStoreTaskEndpointStatusCode200AndTaskCreated()
{
    $client = static::createClient();
    $client->request(
        "POST",
        "/tasks",
        [],
        [],
        [
            "CONTENT_TYPE" => "application/json",
            '{"description": "Goodbye, world!", "createdAt": "2012-12-21 00:00:00", "concludedAt": "2012-12-21 00:00:01"}'
        ]
    );

    $obj = json_decode($client->getResponse()->getContent());

    var_dump($obj); // <~ the error message is shown

    $this->assertEquals(200, $client->getResponse()->getStatusCode());
    $this->assertTrue($client->getResponse()->headers->contains("Content-Type", "application/json"));
}

The documentation shows this way to send JSON to the controller for testing purposes. So, why does it fail?

You should pass the content data as seven argument of the request method as example:

$client->request(
        "POST",
        "/tasks",
        [],
        [],
        [
            "CONTENT_TYPE" => "application/json",
        ],
            '{"description": "Goodbye, world!", "createdAt": "2012-12-21 00:00:00", "concludedAt": "2012-12-21 00:00:01"}'

    );

PS: I suggest you to check if the json_encode find errors by checking

$obj = json_decode($client->getResponse()->getContent());

if (false === $obj) {
   // Invalid json provided
}
