JavaScript API: Custom visuals not rendering

jamesdales — Mon, 09 Jan 2017 16:33:32 GMT

I'm having a problem rendering reports with custom visuals using the JavaScript API. The report is hosted in the Power BI service, rather than Power BI Embedded.

The rest of the report renders fine. Custom visuals however do not appear and I get a 401 error:

I then open the same report from within in the Power BI service and then refresh it. Then when I return to my page with the embedded report, and refresh it, everything renders successfully.

Please could someone help?

Thanks

James

Yesterday (some other day, too) I had the same problem with a custom R visual.

Sometimes it works with a browser but doesn't with a different one. Now it's working with both Chrome and Firefox but not in Edge (HTTP401: access denied)

What is the custom visual in your case? At the moment I post, the custom visuals such as Pyramid 3D Chart, Tachometer can be rendered well when embeded.

It affects a number of bespoke custom visuals created using the Custom Visuals API.

I'm not suprised custom visuals from the gallery render correctly as aren't these whitelisted in the service and treated differently?

Seems , that this problem occures when using PowerBI.com(url="https://app.powerbi.com/reportEmbed").

When uploading power bi visual solution to Azure (Power BI Embedded (Azure) url="https://embedded.powerbi.com/appTokenReportEmbed"))

, then these error do not appear and visual is loaded. strange ...

@jamesdales

Could you share any custom visual that can reproduce the problem?

Discovered smth else. When you first open your visual in powerbi.com (visual cashed) and then open same visual through javascript api, then this rendering problem does not occure. If u clear cache and try to open your custom visual again then visual is not rendered. You get bunch of unauthorized errors.
