Hi,
I have a custom visual that shows polygons in Google Maps taken from a geojson file using:
map.data.loadGeoJson()
map.data.loadGeoJson('https://storage.googleapis.com/mapsdevsite/json/google.json');
map.data.loadGeoJson('google.json');
Take a look at the post below.

As a workaround I tried to reference the file from a CDN:
map.data.loadGeoJson('https://storage.googleapis.com/.../google.json');
but now it throws an error that the file request has been 'blocked by CORS policy'.
Access to XMLHttpRequest at 'https://storage.googleapis.com/.../google.json' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
Do I need to configure the debug server in some way?
Thanks
