Hi. I am beating all the day with nuxt and pm2

This works:
su user
user@aet:$ pm2 status

if I enable pm2-startup, the app NuxtAppName get into error loop

I tried to do dirty fix, like creating a bash script, that runs 'pm2 status; pm2 resurrect' as user, but it also fails with same error!
Ok, maybe it's systemd problem I thought. Ok created a cron script and run as user... The same! This error loop. Before the script was named index.mjs, I found somewhere to try to create index.js which imports mjs. not helped.

only running a normal 'user' shell session and running commands pm2 status and pm2 resurrect starts this NuxtApp and it works

How to fix? Please help

ok I fixed it. it tried to start on wrong node version.
pm2 startup gave me
sudo env PATH=$PATH:/home/user/.nvm/versions/node/v20.18.1/bin /usr/local/lib/node_modules/pm2/bin/pm2 startup systemd -u user --hp /home/user

so system node was in priority. I changed it to

sudo env PATH=/home/user/.nvm/versions/node/v20.18.1/bin:$PATH /usr/local/lib/node_modules/pm2/bin/pm2 startup systemd -u user --hp /home/user

and it worked. Please fix pm2 startup script.
