dotenv-expand loads from process.env even when ignoreEnvVars is true

[Toilal]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

When using both ignoreEnvVars: true and expandVariables: true dotenv-expand` still load configuration from environment variables.

Minimum reproduction code

https://github.com/Toilal/nest-config-ignore-env-vars-repro

Steps to reproduce

1. Clone the repository
2. npm install
3. MY_VAR=KO npm run start:dev
4. https://localhost:3000

Expected behavior

This should display OK, but KO is displayed. This means the environment variable is loaded from process.env with the following config.

imports: [ConfigModule.forRoot({
  expandVariables: true,
  ignoreEnvVars: true
})],
