[OpenSIPS-Users] JSON errors

Hi, Brett!

The only problem I can see with your construction is that you do not 
properly initialize the JSON object: $json(foo) = "{}". When the "=" 
operator is used, the "{}" is interpreted as a simple string, not as a 
JSON format. You should have used the ":=" which parses "{}" as a JSON 
format and constructs a proper JSON structure, that is populated 
afterwards with the desired value.
Anyway, I am not sure why you get that bogus "value". When I replicated 
your code, the JSON module returns an error when the $json(foo/bar) 
value is retrieved.

Best regards,
