addSource Style Not Loading

[swissums]

When I use mapboxgl API addSource this.map.addSource('api', { type: 'geojson', data: './map.geojson' }); I get a Style is not done loading Error. I have also tried with data from a localhost url.

Here is my whole component code:

class HomeMap extends React.Component {
  getMap = (map) =>{
  	this.map = map;
  };

  componentWillMount(){
		this.mapOptions = {
			style : 'mapbox://styles/mapbox/streets-v9',
      center: [13.377, 52.499],
      zoom: 9.8,
      dragPan : true
		};
		this.mapStyle = {
      position : 'fixed',
			width : '100%',
			height : '100%',
		};
  }

  componentDidMount(){
    this.map.addSource('baumapi', {
      type: 'geojson',
      data: './map.geojson'
    });
    this.map.addLayer({
      'id': 'baumapi',
      'type': 'circle',
      'source': 'baumapi',
      'layout': {
          'visibility': 'visible'
      },
      'paint': {
          'circle-radius': 8,
          'circle-color': 'rgba(55,148,179,1)'
      }
    });
  }

  render(){
    var mapAccessToken = 'token';
		return (
			<Mapbox
				mapboxgl={mapboxgl}
				accessToken={mapAccessToken}
				getMap={this.getMap}
				style={this.mapStyle}
				options={this.mapOptions}
			>
			</Mapbox>
		);
	}
}

Here is the error tree:
