SpreadsheetApp.getActiveSpreadSheet suddenly stops working - google-apps-script

Question

At first I had the error of my rows being out of bounds? Then I get this error with "TypeError: SpreadsheetApp.getActiveSpreadSheet is not a function" after I tampered a bit.
I'm not sure why my script isn't working. I have one function to just autoresize all my rows and another function to resize my rows a specific amount (this one keeps saying my rows are out of bounds) Both of these functions use to work for my rows, so I'm not sure what changed.
function onOpen() {
SpreadsheetApp.getUi().createMenu('Scripts')
.addItem('Hide columns', 'hideCols')
.addItem('Show Columns', 'show')
.addItem('Auto Resize Rows', 'autoResizeRows')
.addItem('Resize Rows', 'resizeRows')
.addToUi()
}
function hideCols() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0];
var cells = sheet.createTextFinder("Pictures").matchEntireCell(true).findAll();
cells.map(x => sheet.hideColumns(x.getColumn()));
}
function show() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0];
var cells = sheet.createTextFinder("Pictures").matchEntireCell(true).findAll();
cells.map(x => sheet.showColumns(x.getColumn()));
}
function autoResizeRows() {
var ss = SpreadsheetApp.getActiveSpreadSheet();
var dataRange = ss.getDataRange();
var lastRow = dataRange.getLastRow();
ss.autoResizeRows(2, lastRow);
}
function resizeRows() {
var sss = SpreadsheetApp.getActiveSpreadsheet();
var cellss = sss.getSheetByName('Sheet1');
var responseData = cellss.getDataRange().getValues();
cellss.setRowHeights(2,responseData.length, 300);
}
Fixed:
function onOpen() {
SpreadsheetApp.getUi().createMenu('Scripts')
.addItem('Hide columns', 'hideCols')
.addItem('Show Columns', 'show')
.addItem('Auto Resize Rows', 'autoResizeRows')
.addItem('Resize Rows', 'resizeRows')
.addToUi()
}
function hideCols() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0];
var cells = sheet.createTextFinder("Pictures").matchEntireCell(true).findAll();
cells.map(x => sheet.hideColumns(x.getColumn()));
}
function show() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0];
var cells = sheet.createTextFinder("Pictures").matchEntireCell(true).findAll();
cells.map(x => sheet.showColumns(x.getColumn()));
}
function autoResizeRows() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var ssname = ss.getActiveSheet()
var lastRow = ssname.getDataRange().getLastRow();
ssname.autoResizeRows(2, lastRow-2);
}
function resizeRows() {
var sss = SpreadsheetApp.getActiveSpreadsheet();
var cellss = sss.getSheetByName('Sheet1');
var responseData = cellss.getDataRange().getValues();
cellss.setRowHeights(2,responseData.length-2, 300);
}

Answer 1

Because you've a typo in this function:-
function autoResizeRows() {
var ss = SpreadsheetApp.getActiveSpreadSheet();
var ssname = ss.getActiveSheet()
var lastRow = ssname.getLastRow();
ssname.autoResizeRows(1, lastRow);
}
It's getActiveSpreadsheet not getActiveSpreadSheet that's why your code is breaking, change that S to s.
Reference:-
getActiveSpreadsheet
