I need to add google maps api key into my .env file.

I configured my webpack according to this config and use it in my map component.
When I console log this key I can see it in console, But while using it with map, map opened just a second then I got a warning screen.

Webpack file:

  plugins: [
            new Dotenv({ systemvars: true }),
        ],

Map component:

    const { isLoaded } = useLoadScript({
        googleMapsApiKey: process.env.REACT_APP_API_KEY,  
        libraries: [GOOGLE_MAP_PLACES_LIBRARY],
    });

.env file:

REACT_APP_API_KEY : "someKey"

Error that i got after a second
