ingress-to-route controller does not provide any information about failed conversions from ingress to route. This is a big issue in environments heavily dependent on the ingress objects. The only way to find why a route is not created is guess and try as the only information one can get is that the route is not created.

    Route is not created and no error is logged

    En error is provided in the events or at least in the controllers logs. The events are prefered as the ingress objects are mainly created by uses without cluster admin privileges.
