Web App Dependencies (JS, CSS) fail to load when using Istio Gateway and VirtualService
Since You use istio Did you enable sidecar injection in your cluster?
Is there a way to re-route the web app from trying to load dependencies from the base domain and prefix it with "/ui" so that it will load?
If i understand You correctly you could use rewrite, which exist in virtual service.
There is a good example which i found in another stackoverflow question
