Error: Unable to find the controller for path "/login_check". The route is wrongly configured. (LexikJWTAuthentication)

Description

When I'm doing a normal request to my symfony server running on http://localhost:8000/api/admin/login_check it returns the desired jwt token.

However, when I do it with the functional tests (with ./bin/phpunit) I get the following error:

Error: Unable to find the controller for path \"/api/admin/login_check\". The route is wrongly configured.

I also went through the functional test docs.

Bug Reproduced

Don't hesitate to clone or fork this project to test. There is README.md explaining installation steps.

I was also able to reproduce the bug by cloning a working example provided by one of the creators of the lexikjwtauthenticationbundle.

Question

Why is there a 404 route not found for /api/admin/login_check route during Functional Testing but works fine with curl and postman?

Github #610

You have wrong name for content-type header in your test request. It should have name CONTENT_TYPE.

$client->request(
   'POST',
   '/login_check',
   ['_username' => 'lexik', '_password' => 'dummy'],
   [],
   ['CONTENT_TYPE' => 'application/json']
);

Checking is here: vendor/symfony/security/Http/Firewall/UsernamePasswordJsonAuthenticationListener.php::handle

if (false === strpos($request->getRequestFormat(), 'json')
   && false === strpos($request->getContentType(), 'json')
) {
  return;
}

It helps in your "bug reproduced" code at least.
