Error handling and logging in Node-Red

Recently I was helping to set up a Node-Red automation for someone and since it was a remote Node-Red system, I did not have easy access to check logs all the time. And I set up error logging. This is what I cover in this video, and the general concepts of how errors occur and how errors can be handled using a custom flow.

My example flow: https://github.com/nygma2004/km/blob/main/error_handling.json
