app scripts data validation from another workbook - validation

Question

I'm trying to validate cells based on a list from a different sheet in a separate workbook. I tested it by copying the desired sheet into the current workbook, to build the code. I changed all the references to reflect the actual source I wanted and everything seemed fine. when I deleted the copy I then had issues as it seems the data validation was still using the copy even though all the references were changed to the original source.
var DbSheet = SpreadsheetApp.openByUrl(ingredientDbBookUrl).getSheetByName(ingredientDbBookName);
function nameValidation(){
var cell = sheet.getRange(3,nameColumn,recipe.getLastRow(),1);
var list = DbSheet.getRange(3,2,ingredientDbSheet.getLastRow());
var helpText = 'helptxt';
var rule = SpreadsheetApp.newDataValidation()
.requireValueInRange(list)
.setAllowInvalid(false)
.setHelpText(helpText)
.build();
cell.setDataValidation(rule);
is it possible to validate cells from a list in a separate workbook? does the fact that I'm using a bounded script matter?

Answer 1

I did it with this:
function validatefromanothersheet() {
const ss=SpreadsheetApp.openById("Another ssid");
const sh=ss.getSheetByName('Sheet1');
const list=sh.getRange(1,1,sh.getLastRow(),1).getValues().flat();
let rule=SpreadsheetApp.newDataValidation()
.requireValueInList(list)
.setAllowInvalid(false)
.build();
SpreadsheetApp.getActiveSheet().getRange(1,1,10,1).setDataValidation(rule);
}

Yes

No
Why did the validation have errors?
This is likely because once you have "set" the validation on a cell, it doesn't matter what the code is that was used to generate it.
It is like building something from a plan, and then expecting the building to change because you have changed the plan.
You would need to first clear the rule and then build the rule and apply it again with the new source.
Just probably best to not use requireValueInRange(range) as the ranges may get crossed over. But if you are converting it to values as your code demonstrates said above, then it should be no issue.
