When I am submitting sales order record,

using var soId = nlapiSubmitRecord(sorec, false, true);

It is returning this error. Can you guess why ? {\"userEvent\":null,\"internalId\":null,\"code\":\"UNEXPECTED_ERROR\",\"details\":\"An unexpected SuiteScript error has occurred\",\"stackTrace\":{\"[Ljava.lang.String;\":[\"<anonymous>(adhoc$-1$debugger.user:158)\"]},\"type\":\"nlobjError\",\"suppressNotification\":false}"

you can try setting doSourcing to true, and ignoreMandatoryFields to false to see if you get a better error message

Actually , some other script was deployed , due to which that error was coming. Nothing wrong with mine.
