How to simulate click on a react-leaflet Marker in my unit tests?

I have this sample react-leaflet map implementation that renders the map and a marker that can be clicked.

import React from 'react';
import { Map, TileLayer, Marker } from 'react-leaflet';


export default class ScoutPlayers extends React.Component {
  render() {
    const state = {
        lat: 51.505,
        lng: -0.09,
        zoom: 13,
    };

    const position = [state.lat, state.lng]
    return (
      <Map center={position} zoom={state.zoom}>
        <TileLayer
          attribution='&amp;copy <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
          url='https://{s}.tile.openstreetmap.se/hydda/full/{z}/{x}/{y}.png'
        />
          <Marker position={position} value={{id: 5}} onClick={(event) => {console.log(event.target.options.value)}} />
      </Map>
    )
  }
}

And I got a simple unit test that should test the click calls a function.

import { mount } from 'enzyme';
import { Marker } from 'react-leaflet';
import ScoutPlayers from './ScoutPlayers';

describe('when displaying scout players map', () => {
    let scoutPlayers;
    beforeAll(() => {
        scoutPlayers = mount(<ScoutPlayers/>);
      });

    it('should call the api when player marker clicked', () => {  
        const player = scoutPlayers.find(Marker);
        expect(player).toHaveLength(1);
        player.simulate('click');
    });
})

On simulate('click') is get the following error

TypeError: Cannot read property '__reactInternalInstance$iexoharntw' of null

Any ideas on how I could fix this? I thought mount should properly create the Marker element so that it can be clickable.

I had a similar problem using GoogleMaps and its Marker in that the element could not be clicked because it has some properties initialised as null. I guess my other question would be how to properly test this kind of component as it has some critical business logic?
