Spreadsheet reference becomes null in doGet(e) if you try to import repo before assigning name to new GAS script

[derrickrc]

Thanks for this plugin. I encountered a bug where if I create a new spreadsheet, go to script editor, and then try to download my branch before actually naming the script file, I get an error message (Update file failed) - but then after I name the script, the files show up.

However what happens afterward is with doGet(e) after I publish the script, I cannot access SpreadsheetApp.getActiveSpreadsheet(). The reference is null. It seems something happens with the binding in this process.

Perhaps just put this instruction on the main page? Thank you.
