Question

I’m trying to write a basic script which creates a UI. I have reduced it to the following:

function doGet(e) {
  var app = new UiApp.createApplication();

  return app;
}

This throws the error:

Method “createApplication” was invoked with [object Object] as “this” value that can not be converted to type $Proxy811. (line 2)

When run from the script edit page, and when published as a web app

Answer 1

You have to remove new from the 1st function line, i.e. the function should be

function doGet(e) {
  var app = UiApp.createApplication();

  return app;
}
