NodeRed addon not working after update to 2024.12

After updating to 2024.12, apparently NodeRed stopped to working.
Getting following errors:

Flows stopped due to missing node types.

  • server
  • ha-entity-config
  • server-state-changed
  • api-call-service
  • api-current-state
  • ha-sensor
  • ha-zone
  • api-get-history

I noticed “node-red-contrib-home-assistant-websocket” was not up to date and I tried to update it to 0.74.2 but it didn’t fix the issue.

After trying different reboots, I also tried to remove the add-on an to reinstall from scratch.

Installation works, well. Connection is made, but then once opened the UI still getting above problems. I have a yellow icon showing that clearly something is not working, but I cannot figure out what’s the issue.

What do the Node-RED logs show during startup?

In my instance, this was caused by having the node-red configuration attempting to use SSL after the upgrade, but no certificate installed/available. Turning off SSL in the config, or adding certificate details to the configuration could fix this, if your instance is the same?

I have this issue too, nodes unavailable from this pallet, I’ve tried the solution above disabling SSL, I’ve restarted the whole system (rpi4), and can’t see anything in the logs that help.

I’d like to try and uninstall node-red-contrib-home-assistant-websocket and install again, how would I do that, or anything else I can try?
