Perhaps after the April 2017 update, some custom visuals could not been shown on our Power BI web which were working well previously, please reference attached picture for error details. Help would be greatly appreciated!
Which customer visuals are not displayed properly in Power BI Service?
I can see these custom visuals on my side. Not sure if it is fixed on your side now. If it is not fixed, as immediate mitigation you can append “&customVisuals=1” to the end of published report URL to enable custom visuals rendering.
This issue has already been reported to Power BI team internally: CRI 35972354
They are working on it.
