First, Happy new Year.
Hello, I have some problems with node red and don't really find the source of the problem.

Could you please tell me where to look?
I'm running Node Red on a pi4 standalone system, at the moment only node red is installed and running.

Thank you very much in advance.

Did this ever work?
if it did, do you know what you changed?
Are you using HomeAutomation?
Can you create a small flow demonstrating the issue? If so please export it and paste it to a reply

You can start node-red with the --safe option node-red --safe and it won't run anything until you do a reply.

It looks like you have two dashboards installed - node-red-dashboard and node-red-contrib-polymer. If you look at the flow page for node-red-contrib-polymer you will see it is unmaintained and over three years old. I would suggest removing it.

ewelink.

Cannot read properties of undefined (reading '_originalWires')
Subflow.start

subflow ?

Hi, thanks for the prompt reply.

It worked 1 day.
I'm using NR as stand alone.
Removed polymer.

Hi, thank you also for the prompt reply.
I've stopped Ewelink for the moment.
The problem doesn't seem to come again.
Is the WebSocket in NR closed or in Ewelink?

Don't really understand that with the subflow. What does it mean?

and did you change anything after that day?

Installed some nodes and played a little bit :sweat_smile:
it seems that it was the ewelink node, since I've deleted it, it's working :wink:
