Thanks for reporting, but we need some context.

- What nodes do you have installed (check your `package.json` file in `~/.node-red`)
- Version of Node RED
- Version of Node
- OS
- Full Node RED start up log

The error turned up after upgrading nodes.js

I do not know how to list all nodes used, it is 20

That probably explains it. After upgrading nodejs it is necessary to rebuild modules that have compiled components. If you are on a Debian based system (such as Ubuntu or Pi OS) the easiest way to do that is to re-run the install script from [Running on Raspberry Pi : Node-RED](https://nodered.org/docs/getting-started/raspberrypi)

I don't think this is related to the problem you've reported. However, you have 2 nodes installed that have clashing names. The original moment node written by me that has a full readme and was updated a few months ago and a copy written by someone else that has no readme so it isn't clear what it is for and hasn't been updated in 8 years.

As I say, get rid of moment2 and then follow Colin's guidance and do:

```auto
cd ~/.node-red
npm rebuild

```

Then restart and see if that helps.

I believe the script will do that for you.

I think that dashboard may well not be compatible with node-red-contrib-ui-artless-gauge. Unless you have a good reason for using it I recommend the dashboard usually used which is node-red-dashboard.

I have finally got rid of the error. But I did not manage to un-install Moment 2. It is claimed to be in use even after deleting it from the flow where I used it.  
Thanks for your help!

In a command window go into the .node-red folder and run  
`npm remove node-red-contrib-moment2`  
then restart node-red.
