this is not caused by node-red, but by some node you have used in your flow(s)
This is my flow can you tell me which node is causing this error? I'm using OPC UA nodes.
Does the error appear in the debug pane? If yes, then it should show the node name or id above the message. Also if you click on that Id it should take you to the node.
no, this error I received in node-red cmd
Show us the full output when you run the command, including the command you run. Please copy/paste, not screenshot.
In order to make the text readable and usable it is necessary to surround it with three backticks (also known as a left quote or backquote
``` Text goes here ```
