this._layer.getLatLngs(...).flat is not a function URL

[FRANKSADWAR]

Hello, I am using Geoman (my first time), adding the plugin was not a problem, so I added controls such that at one instance one can only use a single drawing feature such as drawCircle, drawMarker, etc., but when it came to drawPolygon and drawPolyline, encountered this issue. How can go about this? Is there any on map click events that could be the cause?

Can you please share a demo? It looks like you are defining a polygon without an array of latlngs:

L.polygon(null)

instead of the correct one

L.polygon([])

Thanks, I found out that on extracting coordinates, latlngs have to be an array of points https://leafletjs.com/reference.html#polygon
