LexikJWTAuthenticationBundle: Unable to create a signed JWT from the given configuration

Hi,

In version 2.4.4 all works fine, but in the 2.5 When I Post to https:/localhost/login_check with valid email and password, and pass to the AuthenticationSuccessHandler.php, i got this error:

{ "error": { "code": 500, "message": "Internal Server Error", "exception": [ { "message": "Unable to create a signed JWT from the given configuration.", "class": "Lexik\\Bundle\\JWTAuthenticationBundle\\Exception\\JWTEncodeFailureException", "trace": [ { "namespace": "", "short_class": "", "class": "", "type": "", "function": "", "file": "/var/www/mumablue/vendor/lexik/jwt-authentication-bundle/Encoder/LcobucciJWTEncoder.php", "line": 41, "args": [] }, { "namespace": "Lexik\\Bundle\\JWTAuthenticationBundle\\Encoder", "short_class": "LcobucciJWTEncoder", "class": "Lexik\\Bundle\\JWTAuthenticationBundle\\Encoder\\LcobucciJWTEncoder", "type": "->", "function": "encode", "file": "/var/www/mumablue/vendor/lexik/jwt-authentication-bundle/Services/JWTManager.php", "line": 64, "args": [ [ "array", { "roles": [ "array", [ [ "string", "STRING" ], [ "string", "ROLE_USER" ] ] ], "username": [ "string", "string2" ] } ] ] }, .......... ] } ] } }

What is the problem?
