When following the dotenv documentation, I cannot get dotenv to load my environment variables correctly.

What I've done:

1. Created a brand new Feather.js app
2. Installed dotenv as per the documentation
3. Added a .env file to both the root folder and the src folder, these just has a MEMES=MEMES-WORKS variable in it
4. Made a test required configuration in configuration.js like this:

   export const configurationSchema = Type.Intersect([
     defaultAppConfiguration,
     Type.Object({
       host: Type.String(),
       port: Type.Number(),
       public: Type.String(),
       memes: Type.String() // Made this required to test
     })
   ])

5. Updated my config/custom-environment-variables.json file like this:

   {
     "port": {
       "__name": "PORT",
       "__format": "number"
     },
     "host": "HOSTNAME",
     "authentication": {
       "secret": "FEATHERS_SECRET"
     },
     "memes": "MEMES"
   }

6. Ran the following at the top of my app.js and index.js file:

   import * as dotenv from 'dotenv'
   
   dotenv.config();

When I start the API, I keep getting this error:

error: Unhandled Rejection ValidationError: validation failed

      params: [Object],
      message: "must have required property 'memes'"
    }
  ],
  validation: true,
  ajv: true
}

I've also tried updating my config/default.json file like so:

{
  "host": "localhost",
  "port": 3030,
  "public": "./public/",
  "origins": [
    "http://localhost:3030"
  ],
  "paginate": {
    "default": 10,
    "max": 50
  },
  "memes": "MEMES_DOES_NOT_WORK"
}

But then app.get('memes') keeps on returning "MEMES_DOES_NOT_WORK".

Changing from:

import * as dotenv from 'dotenv'

dotenv.config();

to

import 'dotenv/config';

does seem to work, but the problem is that I have a .env file that I need to read from a parent monorepo directory. So my actual file needs to look like this:

import * as dotenv from 'dotenv';

dotenv.config({ path: ['../../../.env.development.local', '../../../.env.development'] });

Is there a way to specify the import path when using the import 'dotenv/config'; syntax?
