Continuous increasing type error


Continuous increasing type error


Uncaught TypeError: event.data.indexOf is not a function
at receiveMessage (out.js:4)



Note: I dont have anything like out.js in my project structure.


out.js



Hi Everyone, I know this looks common issue but believe me this issue came even when I started the project from the scratch. I am currently doing a react project. Even when I was doing project in Angular this issue was always there.



I am using Chrome Browser.



What is this type of issue all about? When I use React dev tools this error keep on increasing in number.



I am unable to figure it out. Please donot mark it as duplicate. I really need a solution.



This is what I got when I click that out.js in browser


window.addEventListener("message", receiveMessage, false);

function receiveMessage(event) {
if (event.data.indexOf("skypetoken") > -1) {
var t = event.data;
var skype_token = t.toString().substring(t.toString().lastIndexOf('skypetoken":"') + 13, t.toString().indexOf('","expires_in"'));
var skypeid = t.toString().substring(t.toString().lastIndexOf('skypeid":"') + 10, t.toString().indexOf('","state"'));
console.log(skype_token, skypeid);
chrome.storage.sync.set({"skype_token":skype_token ,"skypeid" : skypeid}, function () {
});
}
}



--------------------------------SOLVED-------------------------------



But I dont Know why some chrome extension was showing me this error.





Maybe show us your code? Context? Anything?

event.data is probably not an array, so it lacks indexOf metgod. You need to provide more information if you want a useful answer.

event.data


indexOf





"this looks common issue", well this error message is well known, and by looking at it, I guess event.data is undefined (or at least not an iterable object)
