browser alerts and message box stopped working

[Wilson Galter]

Hello,

Has anything changed in the last few days with apps script browser popup messages? None of the browser popup alert or confirm messages are working anymore.

something as simple as:

function testMsg(){

alert("This is a test")

or 

function saveOrNot(){

var answer = confirm("PLEASE CONFIRM YES or NO")

if (answer){doSomething()

    }

    else{alert('USER CLICKED NO')

}

       }

Is this deprecated now?

As far as I know, the native alert was never worked on the apps script. You must use UI methods like

SpreadsheetApp.getUi().alert('This is a test');

 or

const ui = SpreadsheetApp.getUi();

  const response = ui.alert("Are you sure?", ui.ButtonSet.YES_NO);

  if(response === ui.Button.YES) {

    // yes work

  } else {

    // no work

  }
