Map loading blank

Hi, Map loading blank from a takeout I did today, have tried a different browser just in case. Just thought I'd let you know. Thanks

same issue here in both current Firefox & MS Edge versions. The following error is thrown in the console:

Uncaught Error: Invalid LatLng object: (NaN, NaN)
    at new o.LatLng (leaflet.js:6:13842)
    at o.latLng (leaflet.js:6:14792)
    at o.LatLngBounds.contains (leaflet.js:6:16454)
    at e._redraw (leaflet.heat.min.js:11:2186)
    at leaflet.js:6:513
