Hello,
We've had a workflow on a Service Catalog item successfully execute for some time now. However, I was notified today that the request isn't completing as it should. After researching various logs and workflows, I found an error that appears to be causing this reported issue.
The error description is "SyntaxError: Empty JSON string (sys_script_include.d2426c9ec0a8016501958bf2ac79c775.script; line 155) "
The script include for the sys id listed above is :
gs.include("PrototypeServer");
var JSON = Class.create();
JSON.prototype = {

};
/**

*/
JSON.stringify = function(value, replacer, space) {
return NativeJSON.stringify.apply(NativeJSON, arguments);
};
And the line mentioned in the error above (155) is
return NativeJSON.parse.apply(NativeJSON, arguments);
I am not well versed in JSON. What is the best way to resolve this error? Is NativeJSON no longer relevant?
I appreciate any insights on this.
Thanks,
