Unable to sign JWT Token programmatically with LexikBundle

I'm implementing Lexik JWT library with Sf 4.1.In my case I have to create a JWT Token when needed for several applications through custom authenticator.I have followed the lexik documentation, however I am facing an issue for couple of hours for signing my token.The only thing different than casual case : I use doctrine-odm insteand of doctrine-orm for using MongoDb.

Here the files :

security.yaml :

security:encoders:    FOS\UserBundle\Model\UserInterface: bcryptrole_hierarchy:    ROLE_ADMIN:       ROLE_USER# https://symfony.com/doc/current/security.html#where-do-users-come-from-user-providersproviders:    fos_userbundle:        id: fos_user.user_provider.username_emailfirewalls:    dev:        pattern: ^/(_(profiler|wdt)|css|images|js)/        security: false    main:        form_login:            provider: fos_userbundle            csrf_token_generator: security.csrf.token_manager        anonymous: ~        logout:            path: /logout            target: /login        remember_me:            secret: '%env(APP_SECRET)%'        guard:            authenticators:                - App\Security\GuardAuthenticator\LoginFormAuthenticatoraccess_control:     - { path: ^/login, roles: IS_AUTHENTICATED_ANONYMOUSLY }     - { path: ^/, roles: ROLE_USER }

lexik_jwt_authentication.yaml :

lexik_jwt_authentication:secret_key: '%env(resolve:JWT_SECRET_KEY)%'public_key: '%env(resolve:JWT_PUBLIC_KEY)%'pass_phrase: '%env(resolve:JWT_PASSPHRASE)%'token_ttl: 3600

LoginFormAuthenticator.php (onAuthenticationSuccess method) :

/** * @param Request $request * @param TokenInterface $token * @param string $providerKey * * @return null|JsonResponse */public function onAuthenticationSuccess(    Request $request,    TokenInterface $token,    $providerKey): ?JsonResponse {    /** @var User $user */    $user = $token->getUser();    $apiToken = $this->jwtTokenManager->create($user);    $user->setApiToken($apiToken);    $this->documentManager->persist($user);    $this->documentManager->flush();    return new JsonResponse(['Authorization' => $apiToken]);}

private.pem :

-----BEGIN RSA PRIVATE KEY-----Proc-Type: 4,ENCRYPTEDDEK-Info: AES-256-CBC,F05739F4D47EE90DADA678BA60000AE4<sensitive data>-----END RSA PRIVATE KEY-----

I tried to inspect parameters passed to create or sign method in vendor :

• The "key" parameter passed is the path string to the file, and it is not working, getting "Unable to create a signed JWT from the given configuration." error

Do you have any piece of advice to help me please ?
