"callback" argument must be a function Node.js

Question

I'm getting this error on "callback", this is the only part of the code where I use it. Thanks.

throw new TypeError('"callback" argument must be a function');

Thank you!

try this client.chatMessage(steamID, Config.options.successMessage, callback); — Tuan Anh Tran

Somewhere you are supposed to be passing a function for a callback, but you are either not passing that argument at all or you are passing something that is not a function. We'd have to see a lot more code to know where that error is. Typically, you would start at the exact source line of the exception and work up the call stack until you find a line of your code that is passing the wrong arguments. — jfriend00

On the following line you should probably pass a reference to callback instead of calling it.

Instead of this:

client.chatMessage(steamID, Config.options.successMessage, callback());

Do this:

client.chatMessage(steamID, Config.options.successMessage, callback);
