Answer 1

Managed to resolve this by retriggering gcloud authorization with:

gcloud auth application-default login

Answer 2

The steps I fixed it:

1. rm ~/.gdrive/token_v2.json as other answer suggested.

2. But I get danger error if I open the link get from gdrive about to re-authorize:

3. So I create a drive project by go to https://developers.google.com/drive/api/v3/quickstart/js and click "Enable the Drive API":

   

4. Click the "API Console" link on that dialog:

   

5. To make default redirect url (i.e. urn:ietf:wg:oauth:2.0:oob) works, we need Installed type app and can't use "Web application type app"(which only allow http/https scheme). So click "Create credentials" and choose "Oauth client ID" item:

   

6. Ensure select "Other" type:

   

7. Copy "Client ID" and "Client secret" from created item. cd to ~/.go/src/github.com/prasmussen/gdrive/, then replace both at this two variables in handlers_drive.go file, save it, e.g.:

       const ClientId = "xxx.apps.googleusercontent.com"
       const ClientSecret = "xxx"
   

8. Then run go install at that directory. Now run gdrive about and open that link in web browser. I get This app isn't verified error page. You are the author who created that app on above steps and suppose safe. Nevertheless simply click "Advanced" link and click Go to Quickstart (unsafe) link:

9. Click "Allow" it, copy/paste the code back to gdrive about and done:

Answer 3

This is because your authorization token has expired.

Currently there is an open Issue to improve this error message here.

You should delete your token with rm ~/.gdrive/token_v*.json then run the gdrive about command to reauthorize
