The function call getNextWorkingDay requires 1 argument.

Error message

The function call getNextWorkingDay requires 1 argument.

What it means

getNextWorkingDay is a Kettle Rhino extension function that returns the timestamp of the next working (business) day after the given date. It requires exactly 1 argument (a Date). Any other argument count triggers this RuntimeError.

Solutions

1. Call with exactly one Date argument: getNextWorkingDay(myDate)
2. Convert string dates to Date objects first (e.g. str2date(...)) before passing
3. Remove any extra parameters from the call

Example fix

// before
var next = getNextWorkingDay(d, 'yyyy-MM-dd');
// after
var next = getNextWorkingDay(d);

if (!(d instanceof Date)) d = str2date(String(d), 'yyyy-MM-dd');
var next = getNextWorkingDay(d);

function isDate(v) { return v != null && v instanceof Date && !isNaN(v.getTime()); }

try { var next = getNextWorkingDay(d); } catch (e) { Alert('getNextWorkingDay: ' + e.message); }

When it happens

Trigger: Calling getNextWorkingDay() with no arguments, or with extra arguments such as a format string or holiday list.

Common situations: Copy-pasted script fragments expecting a locale/calendar parameter; calling the function inside a string concatenation and accidentally passing the concatenated string as a second argument.
