+1 my legacy project pipeline started breaking since a week. Nodejs v10.24.1 with Gulp 4.0.0
Using v6.4.2 didn't work either.

I am also seeing this issue. Same situation: my pipeline that was previously working is now failing here. Adding const { TextDecoder } = require("util"); before the offending line in server.js seems to let the build continue.

This line was added in 6.5.0, but it seems that the proper libraries were not imported: https://github.com/socketio/engine.io/blame/9608781efe32aa4a5f2800923aabc2a3be8c7148/lib/server.ts#L23

Disabled NPM package browser-sync for the time being. This depends on socket.io, which depends on engine.io.

This should be fixed by 6dd2bc4, included in version 6.5.1.

Thanks for the heads-up 👍
