How to use authenticateSession?

[odiwml147]

I want to implement ocpp-1.6-j http auth, server code like this:

@Override
public void authenticateSession(SessionInformation information, String username, byte[] password) throws AuthenticationException {
     System.out.println("identifier: " + information.getIdentifier());
     System.out.println("username: " + username);
     System.out.println("password: " + password);
 }

client code like this:

        JSONConfiguration jsonConfiguration = JSONConfiguration.get();
        jsonConfiguration.setParameter(JSONConfiguration.USERNAME_PARAMETER, "Test025");
        jsonConfiguration.setParameter(JSONConfiguration.PASSWORD_PARAMETER, "123456");
        JSONClient jsonClient = new JSONClient(coreProfile, null, jsonConfiguration);

But The connection will be automatically closed without any exceptions,and the server cannot obtain the username and the password.
So, I would like to inquire about how to use it.

Had the same issue when reading password without precaution. My debugger indicates that when no password has been submited the password variable is null.

So : System.out.println(password != null ? new String(password, StandardCharsets.UTF_8) : "no password");

I found the reason.Because my password is not long enough.OCPP requires a password length of 16 to 20 bytes.

@jmluy I am getting 404 and after calling the authenicatesession I am getting the username and password info when will the next step on the server side authenticate these credentials to start a new session? I would appreciate your quick response.
