package.json env params not loading into app
What's going wrong?
My app fails to start with pm2, due to package.json env params not loading
0|my-app | {"message":"Environment variable 'app.name' is not defined","level":"error"}
0|my-app | {"message":"Environment variable 'app.version' is not defined","level":"error"}
0|my-app | {"message":"Configuration check failed. Exiting","level":"error"}
Same params are correctly displayed by pm2 show 0:
Describing process with id 0 - name my-app

This is my ecosystem.config.js file:
module.exports = {
apps: [{
name: 'my-app',
cwd: '/opt/services/my-app/deploytest/source/my-app/',
script: 'dist/index.js',
watch: true,
ignore_watch: ['node_modules'],
post_update: ['npm install', 'npm run build'],
env: {
ENV_PATH: '/opt/services/my-app/.env',
},
}],
};
The workaround I found is to set ecosystem.config.js script to npm run serve (which just executes node dist/index.js)
but then I lose that info on PM2:

How could we reproduce this issue?
I'm not sure what is causing the issue, but it might be related to my app's folder structure
root
└── my-app
|
├── dist
| └── index.js
|
├── ecosystem.config.js
└── package.json
Just in case, this is my package.json
{
"name": "my-app",
"version": "2.4.2",
"description": "'my-app API'",
"main": "src/index.js",
"engines": {
"node": "=10"
},
"scripts": {
"build": "babel src -d dist --copy-files",
"serve": "node dist/index.js",
"start": "nodemon src/index.js",
},

hi, same issue : how to recover the name and version of the package to use is as display it in response to a front-end ? the "process.env.npm_package_version" displays "undefined" with pm2
