Encountering an 'Uncaught SyntaxError: Unexpected token' error while attempting to parse JSON data

I keep encountering an 'Uncaught SyntaxError' when attempting to parse a JSON string, and the reason behind it remains elusive.

The issue seems to be related to the fact that message is recognized as a string, which is a known problem, even though the json structure appears to be correct. The line causing the failure in my code is var obj = ....

this.send = function (message) {
    console.log(message);
    console.log(message.toString());
    console.log('{"ReadyToGo":1}');
    console.log(typeof message);
    var obj = $.parseJSON(message);
}

Before the error occurs, this is what I see on the console:

{"ReadyToGo":1}
{"ReadyToGo":1}
{"ReadyToGo":1}
string

Any insights or suggestions?

UPDATE: Included console.log(typeof message), returning 'string'

Answer №1

After some investigation, I have figured out the issue. It seems that a null character ( '\0' ) was inadvertently added to the string somewhere within the lengthy function calls, causing it to go unnoticed in the debugger. Special thanks to cookie monster for bringing this to my attention.

Once I removed the null character, everything started working smoothly.
