Regarding power bi createimagebitmap issue in safari after deployment

[vraw-dev]

I have developed django application embedding power bi report using master user and AAD token. Upto development everything is fine, but when i deployed the app using nginx and docker, safari browser got some issue displaying map in power bi report.
I thought my code got some issue so replicated my power bi report using powerbi-developer-sample repo which is using flask and in that case also everything is fine in development but same issue after deployment. 
The issue is that map is not displayed properly and an alternate image is coming up stating - "Could not load image because of an error occured reading Blob argument to createimagebitmap. Please make sure to use a supported image type such as PNG or JPEG. Note that SVGs are not supported.".
I have attached the screenshot as well. Anybody with solution?

Hi @v-pagayam-msft the issue was only when the application was deployed as HTTP for testing purpose and not running on localhost or 127.0.0.1. As soon as app moved over HTTPS, there is no issue.

Hi @vraw-dev ,
Thank you for the update!
Map visuals in Power BI rely on secure connections to load external resources like tiles and images. When the app runs over plain HTTP, especially in Safari (which is a bit stricter with security), it may block those resources , which is why you were seeing that error. Switching to HTTPS resolves it because the browser sees it as a secure context.

Hope this helps.If so,consider accepting it as solution.

Confirm with the tenant admin and capacity admins that map visuals are not blocked on tenant or capacity level.

But its working sometime, which i feel like is either the issue because of cache or race condition
