1.13-1.16 version client team packet modification exception

[MeowRay]

After modifying the prefix of team packet, the client works normally under 1.13 version, but above 1.13, the client json error occurs and there is no server console error

code:

@Override
    public ParseResult<Team> tran(Stream stream, Team packet, ProxiedPlayer player) {
        if (packet.getPrefix() != null) {
            String s = packet.getPrefix().replace("喵喵喵", "meowwwwww");
            if (s != null) {
                if (s.length() > 16) s = s.substring(0, 16);
                packet.setPrefix(s);
                modfiy = true;
            }
        }
        if (modfiy) {
            return new ParseResult<>(packet, true, false);
        }
        return (ParseResult<Team>) NO_MODIFY;
    }

Oh, it seems that prefix and suffix are in the form of json in version 1.13 and above, I am still testing...

Okay.. bungeecord client version 1.8-1.13 team packet prefix is a text, 1.13-1.16 is json. I need to write two parsing methods
