[Bug] Silent Failure of draw.start() (esri-leaflet + TerraDraw)
Describe the bug When using both esri-leaflet and TerraDraw with Leaflet, the draw.start() method shows no response and no error.
Terra Draw npm version [email protected] [email protected]

} else {
return { color: "white", weight: 2 };
}
}
})
.addTo(map);
const draw = new terraDraw.TerraDraw({
adapter: new terraDrawLeafletAdapter.TerraDrawLeafletAdapter({ lib: L, map }),
modes: [new terraDraw.TerraDrawPolygonMode()]
});
document.getElementById("polygon").onclick = function () {
draw.start();
draw.setMode("polygon");
console.log("Drawing started");
};
</script>
</body>
</html>
Expected behavior Clicking the polygon button produces no response; I hope it works properly for drawing.
