Symfony4: Unable to find the controller for path "/api/login_check". The route is wrongly configured

Question

I am tyring to set up symfony4 api JSON login by JWT. The api platform core bundle is installed and I followed this instruction: https://api-platform.com/docs/core/jwt/

I created the custom user provider as described. By opening the URL /api/login_check the error message "Unable to find the controller for path "/api/login_check". The route is wrongly configured." occurs.

By sending a POST request I get the error page in html.

This is my routes.yaml:

#index:
#    path: /
#    controller: App\Controller\DefaultController::index
api_login_check:
    path: /api/login_check

And here is my security.yaml:

security:
    encoders:
        App\Security\User\WebserviceUser: bcrypt
    # https://symfony.com/doc/current/security.html#where-do-users-come-from-user-providers

Does anybody know what my mistake is?

Answer 1

I ran into the same issue, and it appeared that the header

    Content-Type: application/json

must be added when you requesting /api/login_check
