What do these commands show?
`which node`
`which npm`
`apt policy nodejs`
`apt policy npm`

It is kind of the ...... main machine.
I guess I could update it, but.......
I'd have to remember all the stuff I've got installed on it and install them on the new build.
(Not the end of the world.)
I updated form ...... jessie to buster a few years ago.

Everything was working and I was editing code in a subflow.
DEPLOY..... (wait wait wait)..... no response from server.

Yup, been there, done that. I still have one Pi running Bullseye.
Probably best to concentrate on NR just now.
There was a time when you had to install npm seperately but I think that was back at Wheezy.
"Everything was working" Hmm something broke, let's hope it's not the SD card failing.
Stepping back while Colin diagnoses...

I hope the SD card isn't on it's way out.
Haven't had any other problems. I was just .... stupidly ..... trying to get a bit of code working.

Yes, but I do not know what it means.
So wasn't sure if it was a question or statement.

Sorry.
Finger nails are long.
I slightly changed the order only that they are
```auto
which node
which npm
apt policy npm
apt policy nodejs
```
Only that their outputs are small to large.

It was only the one you mistyped originally that we needed.
That all looks ok, what about
`node -v`
`npm -v`

Make sure all your os packages are up to date
`sudo apt update && sudo apt full-upgrade`
Then try the `-v` commands again.

I realise it isn't that, nodejs 18 is the latest supported for buster, so re-run the script but with --node18 instead of 20

It's down to the `Install Node.js 18 LTS` line....
Wow! Done. Moving to next line.
Installing core now.
DONE....

Try running it now?
Or copy the files back first?

Don't you keep image backups of all your SD cards? If not then you should. Then when one fails you just need to re-burn it on a new card.
