See https://developers.google.com/identity/sign-in/web/devconsole-project.\”,\n "errors": [\n {\n "message": "Login Required.",\n "domain": "global",\n "reason": "required",\n "location": "Authorization",\n "locationType": "header"\n }\n ],\n "status": "UNAUTHENTICATED",\n "details": [\n {\n "@type": "type.googleapis.com/google.rpc.ErrorInfo",\n "reason": "CREDENTIALS_MISSING",\n "domain": "googleapis.com",\n "metadata": {\n "method": "ccc.hosted.frontend.directory.v1.DirectoryGroups.Get",\n "service": "admin.googleapis.com"\n }\n }\n ]\n }\n}\n"
