I need to filter the WMS layer included in my map for a date field. Basically I only want to show what has happened after a certain date:

I tried the following, but no luck

createMap = () => {



    addCommonProjections();

    const vectorSource = new VectorSource();





    const vectorLayer = new VectorLayer({

        source: vectorSource

    });





    const baseLayer = new TileLayer({

        source: new OSM()

    });



    this.wms_source = new ImageWMS({

        url: environment.live_lightning_data,

        projection: 'EPSG:4326',

        styles: 'default',

        params: {

            layers: '0'

        },

    });



    const lightning_layer = new ImageLayer({});

    this.map = new Map({

        layers: [baseLayer, lightning_layer],

        target: document.getElementById('lightning'),

        view: new View({

            center: fromLonLat([175.79, -37.79]),

            zoom: 7,

            projection: 'EPSG:3857'

        })

    });



    lightning_layer.filter.greaterThan('data_date_time', '2019/03/02');

    lightning_layer.setSource(this.wms_source);

I know, a little chaotic, but the map map itself displays the data correctly, but it is unhappy with however I try to add the filer.

The way I added it now,results in '... is not a function'

Anyone any suggestions?
