Dear all.

I just started with Node-RED yesterday and it's just... amazing ! I love it. Today I have an issue, after a lot of research I haven't found the issue so here I am

I installed Node-RED on a Raspberry-Pi 3B, so far everything was working until the moment I went to "manage palette" and then I added this package "node-red-contrib-zigbee2mqtt".

The moment I added, some basic nodes just disappeared from the bar on the left, as I was using them I also get the "Flows stopped due to missing node types" msg on the screen. Checking the log at the start it says "Waiting for Missing Types to be Registered" and then indicates indeed the nodes missing.

I tried to "fix it", removing the package "node-red-contrib-zigbee2mqtt" (even if I will need it), however it didn't change anything.

What Am I doing wrong? Thanks a lot and greetings from Belgium 🙂

Welcome to the forum.

What OS are you running on and how did you install node red?

Which nodes is it complaining about?

Hey @Colin !  
Thanks a lot for the response. Based on all the previous post that I have seen before, it seems that the people here is very cool 🙂

**For the OS:**

pi@raspberrypi:~ cat /etc/os-release PRETTY\_NAME="Raspbian GNU/Linux 10 (buster)" NAME="Raspbian GNU/Linux" VERSION\_ID="10" VERSION="10 (buster)" VERSION\_CODENAME=buster ID=raspbian ID\_LIKE=debian HOME\_URL="http://www.raspbian.org/" SUPPORT\_URL="http://www.raspbian.org/RaspbianForums" BUG\_REPORT\_URL="http://www.raspbian.org/RaspbianBugs" pi@raspberrypi:~

**How I installed, Node-RED**  
I basically followed the official instructions and entered this command:

```auto
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)

```

After the installation basically everything was working fine. This is a Raspberry working with an card that was imaged just days ago, it's basically a clean installation. (there **was** something a bit strange at the beginning: when I selected an Item I could not delete it by pressing delete, I needed to double click and then click on delete. Could it be that the installation had something wrong since the beginning?)

**Which nodes is it complaining about?**  
These ones, dear Colin:

_The workspace contains some unknown node types:_  
\*\* mqtt out\*  
\*\* mqtt in\*  
\*\* debug\*  
\*\* switch\*  
_Are you sure you want to deploy?_

Also, I was thinking that this could be useful:  
This is what I see when I start Node-RED:

Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials  
file will not be recoverable, you will have to delete it and re-enter  
your credentials.

## You should set your own key using the 'credentialSecret' option in your settings file. Node-RED will then re-encrypt your credentials file using your chosen key the next time you deploy a change.

I would say that you have a corrupted configuration. What SD-Card are you using? Also, what power supply on the Pi?

The SD-Cards on the Pi's are vulnerable to corruption if using a poor quality card or a power supply that does not have enough "umph". Or possibly a poor quality USB lead if you are using a USB power supply.

Dear @Colin  
A quick update to let you know that I after uninstalling the package that I added, I just reinstalled the Node-RED, with this command

```auto
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)

```

The good news is that now everything is like it was at the begining: All the standard nodes are working fine again, but I don't have what I wanted to add ("node-red-contrib-zigbee2mqtt" )

I wanted to install it again and I noticed this:

_Installing 'node-red-contrib-zigbee2mqtt'_  
_Before installing, please read the node's documentation. Some nodes have dependencies that cannot be automatically resolved and can require a restart of Node-RED._

So indeed, it seems that I need to do some extra steps after the 'node-red-contrib-zigbee2mqtt' is added. I'm checking the documentation ([node-red-contrib-zigbee2mqtt (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-zigbee2mqtt)) and I still don't see anything 😕

=\> How could I know what should be done to have everything working after this 'node-red-contrib-zigbee2mqtt' is added?

Thanks a lot.

That is a standard warning. The documentation for that node does not indicate any pre-installation requirements.

9 people have bothered to give it a 5\* rating on the flows site so it would seem to be working and stable for most people.

If you installed initially using the script you referenced then there is no way that installing a node through the palette manager should be able to cause the loss of core nodes. This is because the core nodes are in an area on disc that cannot be modified without sudo privileges.
