Bug in advance javascript

I have created my own javascript in advance javascript. It works last two weeks but today, it shows an error, FailedSyntaxError: JSON Parse error: Unrecognised token ‘<’.

My javascript is link to google. I run debugger in Google and it works. How do I solve this error?

Hi,

I’d guess the url you’re including from is returning some sort of error as html, which is why you’d be getting an error about ‘<’. If it’s a web app, you should be able to see network traffic from the debugger to see what the endpoint is returning.
