After Node-Red update : Flows stopped due to missing node types. * mqtt-config

[Tinchen9b]

Hello,

I have run today an update on Node-Red and also zigbee2mqtt nodes and since then I am getting following error:

Flows stopped due to missing node types.

• mqtt-config

I have tried to run the update the second time - no change.
Can I roll back?

I have also tried to delete all, but did not helped.
Any idea how to resove it? It is a bit bigger project, so I can not just deinstall it all and delete..

Thank you!

Hi @Tinchen9b welcome to the forum.

Can you stop Node-red and then start it again and copy the startup log and paste it to a reply.
Also what version of Pi are you runing (use cat /proc/device-tree/model)
and what linux release (use cat /etc/os-release)

Can I roll back?

Node-RED saves one backup when you hit deploy. So unless you have deployed only once, you would have to go to a maual backup...if you have any.

I was able to find it in the right menu and then delete it from there. It was not visible on the UI

Now its is gone, it works again.

That is because it is a configuration node. This is explained in the documentation: Node-RED Concepts : Node-RED
