[keycloak-dev] Customizing error Pages(for example client log)

Hi All, We are trying to customize the error pages based on the realm id. We are able to do the basic modification by extending the error pages in our custom theme. But in our error pages we wanted the have more realm specific customization(for example customer logo) by fetching the logo from external services based on the realm Id. Currently we don't see a way by looking at the code. Any help is appreciated Thanks Rony Joy
