PM2 with NodeJS crash after few minutes and restart in loop – Debian

I have a NodeJs+Express+Mongodb app and I’m trying to run it on my vps.
I do :

pm2 start server

[PM2] Applying action restartProcessId on app [server](ids: [ 1 ])
[PM2] [server](1) ✓
[PM2] Process successfully started

Current process list running is not in sync with saved list. App app differs. Type 'pm2 save' to synchronize.

Everything works fine. But after few minutes pm2 has an error and restart in loop every 1 second :

Can someone help me to understand what’s wrong ? Everything works fine in localhost but make it works in production is very hard for me.

    Try and start your app without PM2, usually this indicates the node instance is failing so doing a regular node [appname] will generate where your node app is failing, probably a missing package.

    Read the message: the running process is not synchronized.

    You need to pm2 save.

    Follow the appropriate documentation.
