Home Assistant Community Add-on: Node-RED

I’m getting this error when importing flows from ChatGPT or Claude…

This node is a type unknown to your installation of Node-RED

I searched but did not find any mention of this error or solutions.

I installed Node-Red from using info from this thread which says " The add-on is pre-configured out of the box! There is no need
to add/change/update the server connection settings!"

Do I need the Node-RED Companion Integration?

TIA!
