Does this example work from Google Cloud Shell?

[jwdinkel]

Hello,

Would anybody have some time to help me get the web version this example working, please?

I am able to run this on port 8080 in google cloud shell by modifying the package.json file.
I notice some warnings:

npm WARN EBADENGINE Unsupported engine {
npm WARN EBADENGINE   package: 'karma@0.13.22',
npm WARN EBADENGINE   required: { node: '0.10 || 0.12 || 4 || 5' },
npm WARN EBADENGINE   current: { node: 'v12.14.1', npm: '7.15.1' }
npm WARN EBADENGINE }

I can type text, rename a file, and the buttons at the top right perform some basic actions....

The google drive icon/button at the top right shows this screen:

However, the API behind the angular app doesn't seem to work. For example, when I try to authorize the google drive, I get an error:
docs.google.com refused to connect.

Thank you.
