Hi, I have a report where I used successfully for a long time the Drilldown Cartogram visual. Recently we fund the following error in the visual: `Invalid Json File` . I remove the visual from the project and import it again and now, when I try to use the visual again, it show nothing. Any idea ?
Hi @avaldes ,
Please try to enable AllowOrigin=* to the root of the website where you are reading this topojson file from. If you are using IIS you can add web.config file to your applicaion root.
https://enable-cors.org/server_iis7.html
Adding CORS definitions to web.config file like below.
<system.webServer>
.........
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*"/>
<add name="Access-Control-Allow-Headers" value="Content-Type"/>
<add name="Access-Control-Allow-Methods" value="POST,GET,OPTIONS"/>
</customHeaders>
</httpProtocol>
