Man, that error is the bane of my existence.
One thing that helped me: validating the request *right before* sending it. Use a tool like JSONLint for your payloads, and maybe even a header checker (some IDEs have plugins for this).
Also, is the API RESTful? Sometimes trailing slashes or wrong HTTP methods trigger this code is usually caused by an invalid request.
