Node Red service masked?

I installed node red on Pi 3B latest, current Pi OS 11 64 bit lite, no desktop.

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

I then just wanted to enable nodered so did 'sudo systemctl enable nodered' and the service is masked?

$ sudo systemctl enable nodered.service
Failed to enable unit: Unit file /lib/systemd/system/nodered.service is masked.

$ node -v
v16.19.0

$ npm -v
8.19.3

$ uname -a
Linux test.local 5.15.84-v8+ #1613 SMP PREEMPT Thu Jan 5 12:03:08 GMT 2023 aarch64 GNU/Linux

Any idea?

Does that service file exist? If so then what is in it?

I did not explicitly check, since it was a fresh image, I just imaged the SD card and reinstalled. I believe it was a side effect of the file system had not been expanded, so likely the installed was broken.
