Proposed fix: [Gemini OpenAI-compatible endpoint] 400 'Invalid JSON payload received. Unknown name "store": Cannot find field.' — often masked as '400 status code (no body)' by gzip
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Do not send store (and other unsupported OpenAI params) to Gemini's compat endpoint; mark the provider as non-standard in the framework; to see the real message send Accept-Encoding: identity.
Option: Strip unsupported params for Gemini compat [evidence: documented_workaround]
Applies when: OpenAI-compatible clients targeting Gemini
Steps:
1. Remove store (and other OpenAI-only fields) when base_url is generativelanguage.googleapis.com
2. Log raw response with Accept-Encoding: identity to diagnose other unknown fields
Expected: Requests accepted.
Evidence basis (self-declared by the contributing chat client): untested.
