Target range coordinates outside sheet dimensions - google-apps-script

Question

The following code used to work just fine to move rows from one sheet to another based on a criteria in column 7 of the source row.
Now I get the error message that "The coordinates of the target range are outside the dimensions of the sheet."
Would greatly appreciate any help!
Thanks!
function moveDispos() {
Logger.clear();
var ss = SpreadsheetApp.openById("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX");
var sheet = ss.getSheetByName("XXXXXXX");
var startRow = 2;
var lastRow = sheet.getLastRow();
var ColToWatch = 7;
var moves = [];
var data = sheet.getDataRange().getValues();
for (var i = startRow - 1; i <= lastRow - 1; i++) {
var rowVal = data[i][6];
if (rowVal === "XXXXX") {
moves.push(Number(i + 1));
}
}
var moveFrom = "XXXXXXX";
var moveTo = "XXXX XXXXXX";
var sourceSheet = ss.getSheetByName(moveFrom);
var targetSheet = ss.getSheetByName(moveTo);
for (var i = 0; i < moves.length; i++) {
move(moves[i] - i, sourceSheet, targetSheet);
}
}
function move(sourceRow, sourceSheet, targetSheet) {
var sourceRange = sourceSheet.getRange(sourceRow, 1, 1, sourceSheet.getLastColumn());
var targetRange = targetSheet.getRange(targetSheet.getDataRange().getLastRow() + 1, 1);
sourceRange.copyTo(targetRange);
sourceSheet.deleteRow(sourceRow);
}
