Refresh token expired

[davidraviv]

I use gupload from a cron to upload a backup zip to Google Drive.
After a period where it worked fine, it started to fail with this error message:

$ gupload daily-backup.tar.gz -c Backups
------------------------------------------------[ Checking credentials.. ]------------------------------------------------
=====================================[ Error: Something went wrong, printing error. ]=====================================
{
  "error": "invalid_grant",
  "error_description": "Token has been expired or revoked."
}
If refresh token has expired, then use --oauth-refetch-refresh-token to refetch refresh token, if the error is not clear make a issue on github repository.
==========================================[ Error: Credentials checking failed ]==========================================

I have a refresh token in the .googledrive.conf but I understand it has expired.
How do I use the option --oauth-refetch-refresh-token?
I tried it in several ways and it seems that this option does not exist.
How do I refech the refresh token?

$ gupload daily-backup.tar.gz --oauth-refetch-refresh-token
gupload: --oauth-refetch-refresh-token: Unknown option
