我正在尝试查找和更新没有end_date字段的文档。这是密码

export const updatePlayData = async (gameId, updatedPlayDataKey, updatedPlayData) => {
    try {
        const query = {
            _id: gameId,
            end_date: {"$exists": false}
        };

        console.log(query);
    
        const update = {
            $set: Object.keys(updatedPlayData).reduce((accumulator, key) => {
                accumulator[`play_data.${updatedPlayDataKey}.${key}`] = updatedPlayData[key];
                return accumulator;
            }, {})
        };
    
        const doc = await GameData.findOneAndUpdate(query, update, { upsert: true, new: true });
        
        if (doc === null) {
            return { type: "failure", message: doc._id + " could not be updated." };
        } else {
            return { type: "success", message: doc._id + " Game Instance has been updated." };
        }

    } catch (err) {
        logger.error(err.name + ": " + err.message);
        return { type: "error", message: "Internal Server Error. Contact administrator." }
    }
};

这就是我得到的错误：CastError: Cast to date failed for value "{ '$exists': false }" (type Object) at path "end_date" for model "gameData"。
查询没有被修改，所以我确信这不是查询的问题。如果我删除end_date检查，更新将正确发生。
任何帮助将不胜感激。
