What's "EIO: i/o error, write" in node.js and how do I eliminate it?

I have a node.js app using elasticsearch to gather error data and notify relevant stack holders. It starts to give me errors lately (no change has made to the code):

write EIO
Error: write EIO

    at writeGeneric (internal/stream_base_commons.js:145:3)

    at ClientRequest.emit (events.js:315:20)

I suspect this has to do with some type of I/O error on the disk. What can I do to eliminate the error? I am using Node.js v14.0.0 and elasticsearch (npm package) 16.7.1.

This turns out to be a bug in ElasticSearch's log feature due to the fact it is writing to the stdio synchronously. We will either have to turn off the log or use a third party logger.
