Stream closed EOF for parabol/parabol-predeploy-8glj6 (parabol-predeploy)

This should have failed, because if pre-deploy does not fail and exit with a code different than 0, the release is carried on, and it deploys the new Web Servers and GQL Executors, which could cause downtime.

Acceptance Criteria (optional)

Pre-Deploy fails if there is an error.
Triage is performed to find the root cause of the bug, timeboxed to ~1 hour.

Estimated effort: 1 hour to triage. More if root cause is already identified.

@rafaelromcar-parabol The output is misleading. We're logging the error for debugging purposes, but we're retrying all 520-530 errors. As you can see by the line
