fetch external link

dm-p I could not fetch while developing this , I had to locally bundle the json, I was wondeing is there a workaround to fetch external link ?

const TOPO_URL = 'https://cdn.jsdelivr.net/npm/world-atlas@2/countries-110m.json';
const world = await fetch(TOPO_URL).then(r => r.json());

 

Thank you in advance.

    Hi smpa01,

     

    Did you enable the web access privilege? This is the first thing I'd check.

     

    This doesn't necessarily mean a fetch will work, though. A custom visual is still a sandboxed iframe with null origin, even if this is enabled. However, you should get a meaningful error in the browser console if you do attempt it. If cdn.jsdelivr.net does not allow cross-origin requests, you won't be able to serve from there and may need to find a suitable server that does.

     

    Regards,

    Bundling the JSON locally is usually the safest solution. Power BI visuals often restrict external URL fetches, so unless the endpoint is explicitly allowed, direct requests may not work.
