Using Dropdown lists on all sheets in a workbook - google-apps-script

Question

I have a dropdown list that is in my workbook in the first tab (Tab titled: Reference Don't Edit) and I have a schedule template (aptly titled "Schedule Template").
I am trying to make the dropdown lists on all of the subsequent tabs (which would be daily tabs) instead of creating a new workbook everyday. I tried changing the dropSS and dropSS_ from using a sheet name to SpreadsheetApp.getActiveSpreadsheet().getSheets() and .getSheet(), etc for use on all active sheets, but it just erases the working dropdown and doesn't put it on the other sheets.
function createPrimaryDrpdwon() {
var dataSS = "References *Don't Edit*";
var dropSS = "Schedule Template";
var primaryDataRange = "A1:A46";
var primaryDropRange = "H4:H";
var primaryDropList = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(dataSS).getRange(primaryDataRange).getValues();
var primaryDropRange = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getRange(primaryDropRange);
var validationRule = SpreadsheetApp.newDataValidation().requireValueInList(primaryDropList).build();
primaryDropRange.setDataValidation(validationRule);
}
function createSecondaryDrpdwon(e){
var dataSS = "References *Don't Edit*";
var dropSS = "Schedule Template";
var dropSS_ = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(dropSS);
var allDataRange = "A1:B46";
var primaryDDCol = 8;
var dropDData = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(dataSS).getRange(allDataRange).getValues();
var activeCell = dropSS_.getActiveCell();
var activeColumn = activeCell.getColumn();
var activeRow = activeCell.getRow();
if(activeColumn==primaryDDCol){
var dep_Col = primaryDDCol+1;
var dep_Row = activeRow;
var depCell = dropSS_.getRange(dep_Row, dep_Col);
var primarySelected = activeCell.getValue();
var validationRule = SpreadsheetApp.newDataValidation().requireValueInList(getDependentList(dropDData,primarySelected)).build();
depCell.setDataValidation(validationRule);
}
}
function getDependentList(dropDData,primarySelected){
var dependenList = [];
var j = 0;
if(dropDData != null){
for(i=0; i<dropDData.length; i++){
if(dropDData[i][0]==primarySelected){
dependenList[j] = dropDData[i][1];
j++;
}
}
}
return dependenList;
}

Try this:
function createPrimaryDrpdwon() {
var dataSS = "References *Don't Edit*";
var dropSS = "Schedule Template";
var primaryDataRange = "A1:A46";
var primaryDropRange = "H4:H";
const ss = SpreadsheetApp.getActive();
var primaryDropList = ss.getSheetByName(dataSS).getRange(primaryDataRange).getValues().map(r => r[0]).filter(e => e);
var primaryDropRange = ss.getActiveSheet().getRange(primaryDropRange);
var validationRule = SpreadsheetApp.newDataValidation().requireValueInList(primaryDropList).build();
primaryDropRange.setDataValidation(validationRule);
}
function getDependentList(dropDData, primarySelected) {
var dependenList = dropDData.map(r => {
if (r[0] == primarySelected) {
return r[1];
} else {
return '';
}
}).filter(e => e);
return dependenList;
}
