[{
    "error": {
        "json": {
            "message": "prepared statement \"preparedConfig\" already exists",
            "code": -32603,
            "data": {
                "code": "INTERNAL_SERVER_ERROR",
                "httpStatus": 500,
                "path": "config.fetch",
                "zodError": null
            }
        }
    }
