The failed to fetch error in this sentry report appears to have happened in /api/auth/proxy.

this route uses isomorphic-fetch directly without retries. We should add a fetch-retry library to this fetch.

Either directly add fetch-retry or use gfetch?

code: https://github.com/ThatConference/thatconference.com/blob/main/src/routes/api/auth/proxy/%2Bserver.js

update:
Reading through the Sentry report again, it loos as though the call to https://thatconference.com/api/auth/proxy is what is generating the failed to fetch error. It doesn't appear that https://thatconference.com/api/auth/proxy was called in this case. It failed to be called.
