Heatmap layer manipulation

[JeffJway]

Hi,

I may be missing the section in the documentation on these, but i am having a few problems and can't find out where to look for the answers.

First, after creating a instance of the heatmap

var stuff = {
"radius": 1,
"scaleRadius": true,
"useLocalExtrema": true,
latField: 'lat',
lngField: 'lng',
valueField: 'count'
};

var data = {
max: 10,
data:[{ lat: 5.102, lng: 85.112, count:5}, { lat: 5.202, lng: 85.312, count:5})]};

var heatmapLayer = new HeatmapOverlay(stuff);
heatmapLayer.setData(data);

map.addLayer(heatmapLayer);

One, later, calling
map.removeLayer(heatmapLayer);
does nothing at all. No errors, but the heatmaps are still there in the map. I want to hide the layer so the user can view the map without the heatmap obscuring, and also unhide it later without needing to recreate the heatmap. It's toggling through a leaflet button.

Two,
How do I remove the heatmap permanently (unlike hiding it above)? doing a setData([{}]) seems to create errors of invalid lat lng

Three,
I don't know if it's my map size or scaleRadius or useLocalExtrema, but I can't seem to create a very small heatmap to cover an area of about 100 meters radius. the smallest I can get is about a few kilometers in radius and sometimes i get errors like:
Failed to execute 'drawImage' on 'CanvasRendering Context2D': The image argument is a canvas element with a width or height of 0.

Lastly,
How do I later get a referrence to this heatmap object? Say I create the heatmap in my Main.js using
var heatmapLayer = new HeatmapOverlay(stuff);
How do i later referrence this Layer in , say a Leaflet or another Javascript file? I can't just get object by elementid, right?

Can anyone enlighten me?
Thanks

Hello,
I am also trying to remove the heatmap layer using the code
map.removeLayer(heat);

But it does not seem to work. I get the following error when I try it.

Uncaught TypeError: Cannot read properties of undefined (reading '_leaflet_id')

And when I try to print out the layer using the console.log(heat); It gives me undefined.

In short, the layer is added properly to the map and I can see it. It also shows the data perfectly as expected. But when I try to remove the layer, it shows the error mentioned above. Is there any way I can solve this or am I missing something?

Any help will be appreciated!
Many Thanks!
