node-red-contrib-minio-all-fix

This is based on the "node-red-contrib-minio-all" package by Colin Payne, but fixes its github issues 1 and 5.

THIS LIBRARY WILL BE DELETED AFTER THE PROPOSED CHANGES ARE INCLUDED INTO THE ORIGINAL LIBRARY!

The following README is from the original package:

NodeRed Node for common MinIO operations, by Colin Payne.

This node utilises the MinIO JavaScript API (please see https://docs.min.io/docs/javascript-client-api-reference.html).

Please Note: This set of nodes (and associated support information) is a work in progress.

The Bucket Notification Operation setBucketNotification is being worked on, and is not currently functioning correctly.
