Response-google-maps: cannot get borders

I have the following react component that loads a GoogleMap from the "react-google-maps" library. I am following the documentation examples but getting undefined from the getBounds () function. I think it has to do with trying to get the bounds before the map is fully loaded, but cannot find a solution.

@inject("map") @observer
export default class Map extends Component {

    constructor(props) {
        super(props);
    }

    render() {
        const mapStore = this.props.map
        const GettingStartedGoogleMap = withGoogleMap(props => (
            <GoogleMap
                ref={props.onMapLoad}
                style={{
                    height: 100,
                    width: 100,
                }}
                defaultOptions={{ styles: this.mapStyles }}
                defaultZoom={mapStore.zoom}
                defaultCenter={{ lat: mapStore.center.lat, lng: mapStore.center.lng }}>
                {
                    mapStore.markers.map(({ lat, lng }) => {
                        return <Marker
                            position={{ lat, lng }}
                            icon={{
                                url: require('../../images/marker.png')
                            }}
                        />
                    })
                }
            </GoogleMap>
        ))

        return (
            <GettingStartedGoogleMap
                style={{
                    height: 100,
                    width: 100,
                }}
                onMapLoad={(googleMap) => {
                    console.log(googleMap.getBounds())
                }}
                containerElement={
                    <div style={{ height: 'calc(100vh - 70px)' }
                    } />
                }
                mapElement={
                    <div style={{ height: 'calc(100vh - 70px)' }} />
                } />
        )
    }
}

      

        
        
        
      

    

Thank you in advance
