Getting 'Uncaught SyntaxError: Unexpected token' trying to parse JSON

Question

I'm getting an 'Uncaught SyntaxError' while trying to parse a JSON string, and I can't figure out why.

It looks like message is a string, which seems to be a common problem, and the json appears to be valid. A snippet of my code is given. It fails on the var obj = ... line.

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

On the console, I get this just before the error.:

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

Any ideas?

EDIT: Added console.log(typeof message), which yields 'string'

Since you're getting "string" from typeof message, then the only thing I could guess would be that there's some invalid invisible character. What happens if you do console.log(message === '{"ReadyToGo":1}');? — cookie monster

stackoverflow.com/questions/18130081/… suggests that your error message is incomplete -- jQuery provides the actual error character at detection. What's the full error? — user1932079

OK, I got this sorted. A null character ( '\0' ) was been appended to the string somewhere along the long call chain, and this wasn't visible in the debugger. Thanks to cookie monster for the heads-up on this one.

Everything works as soon as I strip out the null char.
