is there a particular reason you are using oauth2client? It has been deprecated for several years in favor of google-auth (link). Most of the example code seems to use the newer libraries, so might be easier to diagnose going forward if the newer recommend libs were used.
Are you planning on switching to google-auth?
It could lessen the amount of issues created in this repo
