Error importing custom visual to Power BI Service

[ricardolo]

Hi!

I have developed a custom visual and when I use Power BI Desktop to import the custom visual it works, when I upload the report file (with the custom visual embedded) to Power BI Service it all works ok also.

However, when I use the Power BI Service to import the custom visual to a report from a file it occurs an import error "An error occurred while attempting to import visual in this report."

I see two errors in the browser dev tools (Edge or Chrome) 

SEC7120 [CORS] error in 'https://wabi-brazil-south-redirect.analysis.windows.net/powerbi/content/visual'.

HTTP413 PAYLOAD TOO LARGE

The pbiviz file has a size of about 2.9MB. Is that too much?

I don't know how to fix those problems as they appear to be restrictions from the server.

Can you shine some light on this, please?

Thanks.

I have simply reduced the package size to about 1.6MB with JS minimization and the problem is now solved!
