More informative error when JSON attribute has wrong syntax

Dear all

I have a problem in modification of attributes in JSON format,

With a fairly complex attributes in JSON format of ROLE, if I made an
error (e…g missing comma, curly brace, apostrophe ) , the knife
command does not point
out the location near the error, so it is very difficult to find out
and correct it.

Is it anyway to get a better error message , perhaps by using better
JSON parser to parse it in advance?
