NodeRed won't start - missing node types

I have what seems to be an intermittent issue. Every once in a while when I restart HA, NodeRed fails to start flows with the error: “Flows stopped due to missing node types - service”. I install node-red-contrib-home-assistant-ws from “Manage Pallete” and NodeRed starts. Any ideas why this keeps occurring after reboot and how to fix it?

Uninstall that version and use node-red-contrib-home-assistant-websocket

Thanks for the info! Upon checking, it looks like I do have node-red-contrib-home-assistant-websocket, and also node-red-contrib-home-assistant-ws installed. The “ws” version is still in use. How can I find where this module is used in my flows so I can replace it with the “websocket” version?

I selected the “i” icon in the top right, and in the search flows dropdown list, selected “Unknown nodes”. This allowed me to find the nodes with the ws module and remove them.
