Error while calling a method in cluster.js is : Security policy is you must post to get JSON

We are getting this error:

Security policy is you must post to get JSON

This is with some function in cluster.js being called to get JSON results. Can anyone give some hint as to what this er开发者_运维知识库ror is and what can be the possible solution?

Seems you must do an XHR POST to retrieve the results.
