Hi,
I am using Highcharts static maps. I am facing problem with Belgium map. Other country maps are loading properly but when i select Belgium country then highcharts is throwing error as "Highcharts error #22: www.highcharts.com/errors/22". Can you please suggest me what needs to be done so that map loads without issue and without changing highcharts version
