Constant: string JSON_INVALID = "﷐";

The string constant JSON_INVALID has the value "﷐"

A return value that indicates an invalid 'type' was specified to the llList2Json function.
Also a return value for llJsonValueType function indicating the data type of a given address specifier in a given string-serialized JSON object.
Also a return value for llJsonGetValue to signify a specifier list attempting to access a nonexistent location within a Json text (see Examples).

Caveats

  • Do not use JSON_INVALID with the llList2Json or llJsonSetValue functions. Otherwise noncompliant, invalid Json text will result.
