What causes this how do i trouble shoot this?

Oops looks like I need to update node...

[DrJeff]

What Node version should we be running? I'm on v19.9.0 having issues going to 24 or 25 using nvm to update

[DrJeff]

Ok I had to do a Distro Upgrade but now running on v20 of NodeJS, but now REM is having another issue with GPIO what should I do?

Ok after all the updates REM still didn't like GPIO pins so UNEXPORTED them and rebuilt REM as new then imported config with proper system PI BookWorm.
