Running etherpad-lite 2.0.3 with Node.js 20

[bugtrapper]

I previously ran etherpad lite 1.8.18 and want to upgrade to the recent version (at the time of writing, 2.0.3).
I made a fresh install and I can succesfully start it by running /bin/run.sh.

My etherpad runs on a server and should be controlled by supervisord. Before, I had a etherpad.ini with

directory=%(ENV_HOME)s/etherpad  
command=node %(ENV_HOME)s/etherpad/node_modules/ep_etherpad-lite/node/server.js  
environment=NODE_ENV="production"  
autorestart=true  
startsecs=60

Now, the server.js is called server.ts, but simply renaming that to server.ts in the .ini doesn't work...

Node.js v20.12.2

I also tried to let supervisor point at /bin/run.sh instead of giving server.ts to node. That starts the process without errors, but gives me a 502 Bad Gateway when trying to access my etherpad via the browser – which does not happen when I run the run.sh directly in the shell.

Any idea what I'm doing wrong? I'd appreciate your help!

NodeJS v20.12.2 (I sadly can't update to 21)
npm 10.5.0
supervisord 4.2.1

Updating this in case anyone else runs into similar problems (thanks to @SamTV12345 for the help)

I updated the .ini as follows:

[program:etherpad]
directory=%(ENV_HOME)s/etherpad
environment=NODE_ENV="production"
command=pnpm run prod
autorestart=true
startsecs=60

And – that's it! 😄
