It's impossible to tell what is the problem since there could be many reasons - add this to your code right before the line in your post, it won't fix your problem but it'll give your more exact info that on what is the problem.

if (response.error) {
      console.log('Error - ' + response.error.message);
      return
}

response does not contain a property data so when you try to get the length of it, Javascript throws an error.

You will want to examine response via console.log().
