not able to authenticate with LexikJWTAuthenticationBundle on Symfony 3.4 - symfony

Question

In my Symfony (3.4.24) project with FOSUserBundle (2.0.2) I installed LexikJWTAuthenticationBundle (2.6.3).
I installed and configured everything like said on the github page.
When running the following suggested curl command
curl -X POST -H "Content-Type: application/json" http://127.0.0.1:8000/app_dev.php/api/login_check -d "{\"username\":\"johndoe\",\"password\":\"test\"}"
I allways get the following 401 response.
The response is the same for a non existing user or wrong password as well as for an existing valid user with correct password.
{"code":401,"message":"Bad credentials"}
My setup is the following:
config.yml:
(if I need to add more details let me know)
lexik_jwt_authentication:
secret_key: "%kernel.root_dir%/config/jwt/private.pem" # required for token creation
public_key: "%kernel.root_dir%/config/jwt/public.pem" # required for token verification
pass_phrase: "%jwt_key_pass_phrase%" # required for token creation, usage of an environment variable is recommended
token_ttl: "%jwt_token_tll%"
security.yml:
encoders:
FOS\UserBundle\Model\UserInterface: bcrypt
...
providers:
in_memory:
memory: ~
fos_userbundle:
id: fos_user.user_provider.username_email
firewalls:
# disables authentication for assets and the profiler, adapt it according to your needs
dev:

security: false
# Login for Lexik Json Web Token Authentication
login:

stateless: true
anonymous: true
json_login:

success_handler: lexik_jwt_authentication.handler.authentication_success
failure_handler: lexik_jwt_authentication.handler.authentication_failure
require_previous_session: false
# API for Lexik Json Web Token Authentication

main:

form_login:

check_path: fos_user_security_check
login_path: fos_user_security_login
csrf_token_generator: security.csrf.token_manager
default_target_path: fos_user_profile_show
always_use_default_target_path: true
logout:
path: fos_user_security_logout
target: default_loged_out_target
logout_on_user_change: true
anonymous: true
switch_user:
role: ROLE_ADMIN
provider: fos_userbundle
remember_me:
secret: '%secret%'
lifetime: 15552000
path: /
access_control:
...
- { path: ^/api/login, roles: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/api, roles: IS_AUTHENTICATED_FULLY }
routing.yml:
...
api_login_check:
path: /api/login_check
So - like said I allways get this response:
{"code":401,"message":"Bad credentials"}
Can anyone point into the right direction on how to fix this?

Answer 1

Everything seems to be OK but I suspect that since you have two providers (in_memory and fos_userbundle) from which of them does Lexik JWT looks for the credentials ? If you don't use the in_memory provider, you should try to remove it.
