Have you done the basics?
Looked at the logs?
Checked you have the latest versions etc?

3

Basics?

I have last versions...
I send what writes down...

Where are logs saved?

4

The logs are saved in different places depending on what hardware you are running on and how you have configured Node-RED.

I'd also try googling the error to see if others have had the same issue...

5

I google it but I didn’t find any solutions to this case. I found in logs same warnings as i wrote down up.

6

Which node are you using? Is it this one? node-red-contrib-opcua This issue would appear to be what you are seeing https://github.com/mikakaraila/node-red-contrib-opcua/issues/36

7

Similar yes... but still without solution. I am using node-red-contrib-opcua
Here is also warning on node-red start.

> [warn] [node-red-node-pi-sense-hat/sensehat] Error: Can't find Sense HAT python libraries. Run sudo apt-get install sense-hat

so if you still have the problem, recheck that you have the latest version and then open an issue so that the developer is aware.

Your new issue is because you haven’t followed the instructions in the Nodes ReadMe. The message tells you what you need to do.
