Cannot read property 'includes' of undefined

Question

I am new to JavaScript, am I was trying to dissect an embedded message. Here\'s my code, it runs fine for a few mins, works accordingly but idk what goes wrong.

Answer 1

You can write your code more defensive like this. Instead of

if(message.embeds[i].title.includes("text!"))

you can write the following

if(typeof message.embeds[i].title === "string" &&
message.embeds[i].title.includes("text!"))
