    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>
