The net.createServer documentation indicates that the method takes an options object. The description of the options indicates that there are five possible attributes. The @types/node net declaration of the ServerOpts interface contains only the first two attributes (allowHalfOpen, and pauseOnConnect). Unsurprisingly, attempting to set one of the other options incurs a typescript error. This appears in the 18.7 version of the documentation and earlier.
