Exception: Cannot call FormApp.getUi() from this context-CodePudding

I'm new to google script, and I keep getting the same error (in the title). I have tried to open the form in both editor and preview mode, and have moved to code to the onOpen() function. Here is the code that gives the error:

function onOpen(e){
  FormApp.getUi().createAddonMenu().addItem('Settings','show').addToUi()
  ScriptApp.newTrigger('submit').forForm(FormApp.getActiveForm().getId()).onFormSubmit().create()
}
function show(){
  ...
}
function submit(){
  ...
}

All I had to do to get it working again was remove the code, run the project, then add it back in.

CodePudding user response：

You should never create triggers inside the onOpen method as it is a simple trigger and will fail for users who have not authenticated the script.

If the script is authenticated, it will try to create a trigger everytime the form is opened in the Google Forms editor and may cause your script to fail.
