CORS error when viewing Published PowerBI Report

rpalexf — Thu, 20 Oct 2016 05:51:22 GMT

Hi,

We are planning to embed PowerBI in an Angular2 app and have started publishing reports using the "Publish to Web" function.

When we load just the published url in the browser (eg. https://app.powerbi.com/view?r=eyJrIjoiM2QwOGU3YmMtMjlkNC....) we receive CORS errors in the browser.

The errors displayed are purely from the PowerBI site with no extra embedding used.

"XMLHttpRequest cannot load https://wabi-south-east-asia-redirect.analysis.windows.net/powerbi/metadata/models. Request header field X-PowerBI-ResourceKey is not allowed by Access-Control-Allow-Headers in preflight response."

These also occur multiple times after the load and sometimes causes the report to crash and then reload.

Is this an issue with the report or configuration we are using, or is this a known issue?

Thanks in advance for your time,

Alex

I don't get that error when load the published url in a brower, could you try this url?

The eg url is truncated, please post the completed one so that I can test and try to reproduce the error.

Thanks for the reponse.

I just tried your url in my browser and I get a CORS error in your URL.

I work in Australia, so maybe the CDN where the JS is hosted is not a trusted site for the .com domain.

But I cant be sure.

I also tested your URL in Edge and have the same issue.

Here is the stack track from Chrome;

ai.0.js:1 OPTIONS https://df-msit-scus-api.analysis.windows.net/powerbi/metadata/models XMLHttpRequest.send @ ai.0.js:1(anonymous function) @ powerbiportal.dependencies.bundle.min.js:115n @ powerbiportal.dependencies.bundle.min.js:111(anonymous function) @ powerbiportal.dependencies.bundle.min.js:108(anonymous function) @ powerbiportal.dependencies.bundle.min.js:143$eval @ powerbiportal.dependencies.bundle.min.js:157$digest @ powerbiportal.dependencies.bundle.min.js:154$apply @ powerbiportal.dependencies.bundle.min.js:158(anonymous function) @ powerbiportal.dependencies.bundle.min.js:171e @ powerbiportal.dependencies.bundle.min.js:57(anonymous function) @ powerbiportal.dependencies.bundle.min.js:60

Is there anything else I can try here?

Thanks again for your time,

@rpalexf

Thanks for that clarification. I can verify that the url can be accessed from China and USA.
As I don't have much knowledge on CDN, I'd suggest you submit that issue and ask MS for support.
