I wouldn't think so.
Remember that JSON doesn't actually define anything really: all JSON is
normal, everyday, plain-jane JavaScript literal notation. Nothing more,
nothing less.
The braces represent an object and that's your problem. What your string is
saying is that you have an object and that object has a property called
"errors" which is also an object and THAT object has a property called
"null" which is illegal.
You can't define the "outer" name of an object in JSON (or really in
anything) since it has to be assigned to a variable in the caller but to get
close to what you want you would need something like this (this is from
memory so don't take it at face value):
{"errors":null}
or
{"errors":{}}
I think the latter is closest to what you're looking for.
