Error running remote compact task: { "error": { "message": "Unknown parameter: 'prompt_cache_retention'.", "type": "invalid_request_error", "param": "prompt_cache_retention", "code": "unknown_parameter" } }
It's odd because the last compaction worked not that long ago. Compaction has been working fine on this latest update. Compaction isn't working fine on this latest update. It just randomly seemed to not work for this specific one.
