500 error if backup code is incorrect

[matthew-white]

While setting up backups using Frontend, if the confirmation text you enter is incorrect, Backend returns a 500 with the message "Completely unhandled exception: Cannot read property 'data' of undefined".

From a first look, it seems that Google returns an object with a property named response, but Backend expects a property named res:

central-backend/lib/resources/config.js

Lines 71 to 73 in e9ffd2c

	.then((actor) => (!isBlank(body.code)
	? google.auth.getToken(body.code)
	.catch((error) => reject(Problem.user.oauth({ reason: `Unexpected error received: ${printPairs(error.res.data)}` })))

I think this explains this Sentry issue: https://sentry.io/organizations/getodk/issues/1875192039/?project=1298632
