Why doesn't Open API initialization work?

Question

JavaScript

I'm trying to initialize the API like this:

VK.init({
    apiId: 5213033
});

Error in console:

Uncaught TypeError: Cannot read property 'insertBefore' of undefined

What am I doing wrong? Such an ID definitely exists, I copied it from VKontakte

Answer 1

It's simple: you have this code executed before the body tag is loaded , but should be executed after . For some reason, this was not taken into account in the documentation. So, change your code snippet to something like this

document.addEventListener("DOMContentLoaded", function () {
    VK.init({
        apiId: 5213033
    });
});

Somehow a very small key for api. But the error is strange. In which file does it appear. Drop the code.

Answer 3

regardless of the application number - I have the following in the console:
at the same time - INITIALIZATION works fine, I think the "error" of the vk developers is not critical, and your code has nothing to do with the alarm in the console,
maybe you meant AUTHORIZATION?
