Argument of type 'typeof Environment' is not assignable to parameter of type 'Environment'

Code:

enum Environment {
    Production = 'production',
    Development = 'development',
    Test = 'test'
}

export class Config {
    public constructor(EnvProd: Environment = Environment.Production, EnvEnum = Environment) {
        Config.createConsoleLog(EnvProd, EnvEnum, console);
    }

    private static createConsoleLog(EnvProd: Environment, EnvEnum: Environment, console: Console): void {
        console.log(EnvProd, EnvEnum);
    }
}

Gets the error:

karlm@karl-Dell-Precision-M3800:~/dev/sg$ npx ts-node application/libs/config/index.ts 
⨯ Unable to compile TypeScript:
application/libs/config/index.ts:9:42 - error TS2345: Argument of type 'typeof Environment' is not assignable to parameter of type 'Environment'.

9         Config.createConsoleLog(EnvProd, EnvEnum, console);
                                           ~~~~~~~

Been trying to figure out why I can't get this to work.

Currently you're sending the whole enum object where enum value expected, hence the error.

If you want to allow passing the "enum object" the signature should be:

private static createConsoleLog(EnvProd: Environment, EnvEnum: typeof Environment, console: Console): void

Pay attention to typeof Environment (enum object is also value)
