ReferenceError: "Drive" is not defined

In Google App Maker, I am writing a function in ServerScript that will convert a user-uploaded Excel spreadsheet to Google spreadsheet. I am using this piece of code (https://stackoverflow.com/a/35597644/9878092), but I am getting

ReferenceError: "Drive" is not defined.

I tried using the line of code that I got directly from the link:

file = Drive.Files.insert(file, xlsxBlob, {

and my own edited version:

file = Drive.Files.update(file, ssFileID, xlsxBlob, {

Where ssFileID is the file id of the pre-made Google Sheet I want to insert the data from a user-uploaded Excel spreadsheet into. How do I fix this error?

You have multiple issues:

1. "Drive" is not defined" error, see this

Open menu from your script ( the place you start with Code.gs) and use : Resources - Advanced Google services and check on the Drive API v2

2. Use files from drive to change and upload

   • your source code can identify the files and used ;
   • define the resources and blob ;
   • enable the Advanced Drive API Service: var file = Drive.Files.insert(resource, blob, ...) ;
