This is a common function that calls the URL on the server:

Turned out a weird issue. This is how it's resolved.

• We had checkboxes at the end of the form. The mentioned issue was occurring when we do not select any of the checkboxes. The request was not getting formed correctly and hence server threw error.
• Added a hidden field at the end of the form (make sure this is the last form field) and assigned some value to it.

That' it. Worked like a magic!
