Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client

[jbolda]

Getting the following error, but only in CI (github actions: https://github.com/thefrontside/frontside.com/pull/143/checks?check_run_id=3175965538#step:6:24 ). It seems to run fine locally on a macbook air. I presume it is a race condition?
