One of my most important chat sessions (ID: 690a1b0d-4224-832a-b77e-628cc565b73a) has completely vanished from the UI. When investigating via Network tab, the server returns a 200 OK status, but the JSON payload contains a NULL mapping object.
Evidence Provided to Support (Cases #07622985 / #07442307):
-
HAR Files: I have captured the exact moment the server fails to provide the chat structure.
-
Privacy Portal Failure: When I try to export my data via the official Privacy Portal, I get an AWS ‘NoSuchKey’ error. This proves the underlying data object is missing or corrupted on OpenAI’s S3/database.
The Problem with Support: I have been in contact with support for 30 days. I keep receiving automated AI responses and Tier-1 scripts telling me to ‘clear my cache’. It is impossible to clear a server-side NULL mapping from a client-side browser.
I am a technical user and I have provided all necessary logs. I need a Senior Backend Engineer to look at the database pointers for my account.
Has anyone else encountered this ‘200 OK but NULL’ bug? How can I get a human engineer to actually look at the logs instead of closing my tickets?"
