I’m losing my sanity over this issue.

I’m trying to run Next.js through PM2 cluster, which should be a pretty standard thing to do.

But it’s not.

I have this error

2024-09-21T23:46:38: PM2 log: App [anglio:0] online

}

Next.js is trying to load env files from /app/ecosystem.config.js/.env.production.local, /app/ecosystem.config.js/.env.local, /app/ecosystem.config.js/.env.production… which dopesn’t make sense.

My ecosystem file is:

module.exports = {
  apps: [
    {
      name: 'anglio', // Name of your app
      script: "./node_modules/next/dist/bin/next",
      args: "start",
      exec_mode: 'cluster', // Cluster mode to enable multi-core usage
      instances: 1,  // Number of instances
      env: {
        NODE_ENV: 'production',  // Environment variables for production
      },
      env_development: {
        NODE_ENV: 'development',  // Environment variables for development
      },
    },
  ],
};

And my Docker file ends with:

CMD ["pm2-runtime", "start", "ecosystem.config.js"]

I don’t know what to do
