Line 152 is this one:
var folder = DocsList.getFolder(SANDBOX);
I believe this is because the DocsList function has been removed, and replaced with DriveApp. Most of the things broken by this change can be fixed by simply replacing DocsList with DriveApp, that is, apart from the getFolder() function.
