Row.EndOfFileReached

Error message

Row.EndOfFileReached

What it means

getEnvironmentVar returns the value of a JVM system property from within JavaScript, and it requires exactly 1 argument (the property name). When ArgList.length != 1 the function throws this Rhino runtime error at ScriptValuesAddedFunctions.java:1629 instead of returning a value. Note the function returns an empty string (not an error) if the property lookup itself fails.

Solutions

1. Call with exactly one string argument: getEnvironmentVar('MY_KEY').
2. Handle the empty-string return for missing properties yourself: var v = getEnvironmentVar('K'); if (v == '') v = 'default'.
3. Remove any extra/default arguments from the call.

Example fix

// before
var v = getEnvironmentVar("MY_KEY", "default");
// after
var v = getEnvironmentVar("MY_KEY");
if (v == "") v = "default";

if (arguments.length !== 1) throw new Error("getEnvironmentVar takes exactly one property name");

null

var v;
try {
  v = getEnvironmentVar("MY_KEY");
} catch (e) {
  v = ""; // treat as missing
}
if (v == "") v = "default";

When it happens

Trigger: Calling getEnvironmentVar() with zero arguments, or with 2+ arguments such as getEnvironmentVar('A', 'B'), from JavaScript in the Script Values step.

Common situations: Passing a fallback default as a second argument (assuming an API that does not exist); accidentally passing an extra separator or option argument; calling with no arguments after refactoring.
