Google Sheets API快速入门（v4）问题

Question

I'm trying to go through the following tutorial: https://developers.google.com/sheets/api/quickstart/nodejs#

And when I get to the step to run the quick start file node quickstart.js I get the following error message: Olivers-MacBook-Pro:incrementum oliverpike$ node quickstart.js

undefined:1

SyntaxError: Unexpected end of JSON input
    at Object.parse (native)
    at /Volumes/github-image/bitcoin-core/quickstart.js:43:39
    at FSReqWrap.readFileAfterClose [as oncomplete] (fs.js:445:3)

quickstart.js is trying to read from ~/.credentials/sheets.googleapis.com-nodejs-quickstart.json but that file is empty which is resulting in the unexpected end of JSON input error.

How do I determine what needs to go in that file?

删除文件，代码将触发else条件进行身份验证。
