Task: investigate why some log entries are no longer filtered out

[jonrandahl]

In the latest gem release, the logs contain additional information which should be filtered out and not exposed while running in production mode.

For example:

{"ts":"2025-09-12T14:31:30.479Z","level":"INFO ","message":"response: vary: \"Accept\"x-response-id: \"10398\"cache-control: \"no-transform, max-age=0\"content-type: \"application/json\"transfer-encoding: \"chunked\"date: \"Fri, 12 Sep 2025 14:31:27 GMT\""}

Investigate why the OPTIONAL keys are being generated
