bson error: Invalid value type : nil

gjy1606 commented 7 years ago

问题出在 bson_encode 上面,因为走到一个无法识别的 bson key 类型分支,我在生产环境下面把这个 table 数据 dump 下来保存到文件,然后在自己机器上重新进行 bson_encode ,但是无法复现问题.

请把版面调好一点，看下面的： Styling with Markdown is supported

看起来是你打包的数组里有洞（nil）。

https://github.com/cloudwu/skynet/commit/d6eb49e4eb05fd8fcade50ca965aa17011530d2c 现在已经完全禁止了字典的 key 使用数字。
