Uncaught SyntaxError: Unexpected token u in JSON at position 0

Question

Only at the checkout and on individual product pages I am getting the following error in the console log:

VM35594:1 Uncaught SyntaxError: Unexpected token u          


        

Answer 1

I had this issue for 2 days, let me show you how I fixed it.

This was how the code looked when I was getting the error:

request.onload = function() {
    // This is where we begin accessing the Json
    let data = JSON.parse(this.response);
    console.log(data)
}

This is what I changed to get the result I wanted:

request.onload = function() {
    // This is where we begin accessing the Json
    let data = JSON.parse(this.responseText);
    console.log(data)
}

So all I really did was change this.response to this.responseText.
