Unable to embed paginated reports

[lnoguera]

Hello community, I have been following the official documentation to embed power bi reports into a .net core web application and I´ve found a problem when embedding paginated reports.

Note that the access token and embed token are being generated correctly (using service principal ) and dashboard style (.pbix) reports get embedded and rendered perfectly well, but whenever I try to embed an rdl report I get the following error (image attached). Also note that the paginated reports work well in the power bi app, the problem is only when I try to embed it in my web app.

Also note that this error happens even when I try to embed a paginated report with no data access at all but just some text.

Has anyone experienced a similar problem? if so, I appreciate any help.

It looks like it was an issue related to the capacity and the SKU we had. Embedding Paginated Reports on Generation 1 required at least an A4 SKU and with Gen 2 we can embed paginated reports from A1 SKU onwards. Once we upgraded to Power BI Embedded Generation 2 the problem dissappeared.

Thanks @lbendlin , it was helpful.

When I run this command chrome.exe --user-data-dir="C:/Chrome dev session" --disable-web-security and open the report in the browser tab that this command opens, the report get rendered well. However this is not a fix for production, so now I´m wondering how to solve this without having to run the command every time a user wants to see the reports. 

If I need to allow CORS in the backend or add the origin to the whitelist, where should I do that? is it in the Azure AD Application that is used to access the power bi rest API´s or where?
