Question People joining chat room

[roughnecks]

Hello

 

My BoT is in a couple group chat rooms and is catching all messages starting with "!" in order to execute commands.

I have an issue every time someone joins the chat room and Steam displays this:

 

 

BoT returns:

UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'startsWith' of null

I thought that "messages" and server_messages were 2 different items, so why the error when my code is:

function parseMessage(groupID, chatID, message, senderID, senderAccountID, sender) {
    if (message && !message.startsWith('!')) {
        return;
    }

Isn't the "joined" stuff a server message? How do I get rid of the error?

 

Thanks as always

Without seeing exactly how parseMessage is called, all I can suggest is that maybe you want that if to be if (!message || !message.startsWith('!'))

Did like you suggested and it looks like it's working fine now! Thanks
