What does the error you mention in your personal project with a JSON parser with libuv have to do with it?
I don't think you know that libuv is not a JSON parser but an asynchronous I/O lib.
Is it a libuv function that is returning this error? What is the function?
Are you a developer? If a colleague says to you: I have a code error, what could it be? Without saying function, method, can you tell him with this little information?
Only if you're a fortune teller...
