TypeError: Cannot reap property 'length' of undefined

Question

semi rookie here

I'm trying to run a script to copy a row from one spreadsheet to another - it works initially, then it comes up with a TypeError.

TypeError: Cannot read property 'length' of undefined copyrange1 @ onedit destination.gs:26 onEdit @ onedit destination.gs:2

I'm looking to multiple functions with three destination sheets based on the value in cell AQ then for it to delete the row from the source sheet.

Any suggestions?

function onEdit(){
  copyrange1();
  copyrange2();
  copyrange3();
}

function copyrange1() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getSheetByName('Position Activity'); //source sheet
  var testrange = sheet.getRange('AQ:AQ'); //range to check
  var testvalue = (testrange.getValues());
  var csh = ss.getSheetByName('Suspended Pending'); //destination sheet
  var data = [];
  var j =[];

  //Condition check in AQ:AQ; If true copy the same row to data array
for (i=0; i<testvalue.length;i++) {
  if ( testvalue[i] == 'Suspended - Pending') {
  data.push.apply(data,sheet.getRange(i+1,1,1,43).getValues());
  //Copy matched ROW numbers to j
  j.push(i);
 }
 }
//Copy data array to destination sheet

 csh.getRange(csh.getLastRow()+1,1,data.length,data[0].length).setValues(data);

//Delete matched rows in the source sheet
  for (i=0;i<j.length;i++){
  var k = j[i]+1;
  sheet.deleteRow(k);

//Alter j to account for deleted rows
  if (!(i == j.length-1)) {
  j[i+1] = j[i+1]-i-1;
}
}
} 

Thanks in advance
