Hey. I am trying to run Node-Red on my raspberry pi 4 but I am getting error:

Flows stopped due to missing node types.

- serial-port

In the Node-Red terminal I have the following issue which I cannot solve and could use your help:

Welcome to the forum.  
I guess you have upgraded nodejs. You need to follow the advise in the error. Go into your .node-red folder and run  
`npm rebuild`  
You may also need to the re install node red  
`sudo npm install -g --unsafe-perm node-red`

In fact probably easier to run the pi install/upgrade script from the node red docs.

Edit: Back at my PC now (was on phone), the upgrade script is at [Running on Raspberry Pi : Node-RED](https://nodered.org/docs/getting-started/raspberrypi)
