A potential cause error

[FTYears]

When a player says'[][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][]' My bot stop working and lost connection after a while with no error reporting. That's why and how can I avoid it?
ps:Even the basic bot without bot.on('message',....) has the error. I test in my own pc(16g), I'm really confused. Thanks for your help.
