      When I try to access the same url for a second time, everything works as expected.

      The error happens in these quickstarts:

      • keycloak-httpservice
      • keycloak-whiteboard
      • keycloak-whiteboard-blueprint
      • keycloak-war

          relates to

          Enhancement - An enhancement to or refactoring of existing functionality that is not configurable by an end user (typically a change made by an internal team that affects users) ENTESB-9199 Quickstart tests should fail when it's not properly configured

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
