authenticateSession always receives a null byte array password

[EltonSaraci99]

I am trying to implement the ServerEvents method "authenticateSession" to provide an authentication layer for my backend anytime a charge point tries to connect. The method that I am talking about:

`@Override
public void authenticateSession(SessionInformation sessionInformation, String s, byte[] bytes) throws AuthenticationException {

			log.info("identifier: " + sessionInformation.getIdentifier());
                             log.info("password in byte array: " + bytes);

		}`

However, for some reason, the password byte array always comes as a null value, despite me adding a password in the charge points that I have (tried with several different wallboxes, choosing basic auth). Is there something I am missing? No exceptions get thrown.
