Reference local geojson file in custom visual

Hi,   I have a custom visual that shows polygons in Google Maps taken from a geojson file using:   map.data.loadGeoJson()   as described here: https://developers.google.com/maps/documentation/...
Need Help

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
