Notifiers and "ESPIPE: invalid seek, read" errors

[fivdi]

Attempting to use Notifiers with Node v8.10.0 will result in the following error:

events.js:183
      throw er; // Unhandled 'error' event
      ^

Error: ESPIPE: invalid seek, read

With Node v8.9.4 Notifiers work correctly and there are no errors.

Under the covers a Notifier is a named pipe created by the pigpio C library by calling mkfifo. On the JavaScript side a read stream is used to read notifications from the named pipe.

This appears to be related to nodejs/node#19240

This issue has been fixed in Node.js. Tested with Node.js v8.11.3 and Notifiers works as expected.
