Issue with Drilldown Cartogram visual

[avaldes]

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>
