options is not defined

[MeMyselfI]

I have tried to run the example on my map but I get the following error in Chrome:

webgl-heatmap-leaflet.js:143 Uncaught ReferenceError: options is not defined
at _scalepx (webgl-heatmap-leaflet.js:143)
at e.draw (webgl-heatmap-leaflet.js:111)
at e._update (webgl-heatmap-leaflet.js:84)
at e.s (leaflet.js:5)
at e.fire (leaflet.js:5)
at e.invalidateSize (leaflet.js:5)
at e. (leaflet.js:5)

seems that the scope is not correct but I don't know why it works on your page and not in my one. Here's my code:

var mymap = L.map('mapid').setView([48.7807626,9.0017757], 9);
L.tileLayer('https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token=pk.eyJ1IjoibWFwYm94IiwiYSI6ImNpandmbXliNDBjZWd2M2x6bDk3c2ZtOTkifQ._QA7i5Mpkd_m30IGElHziw', {
maxZoom: 18,
id: 'mapbox.streets'
}).addTo(mymap);

var heatmap = L.webGLHeatmap({
size: 50,
units: 'px',
alphaRange: 0.4
});
