Unable to create Openshift Route | the API version in the data (v1) does not match the expected API version (route.openshift.io/v1)

[cedar715]

We upgraded Fabric8 from 4.1.1 to 4.7.0. All the manifests are getting applied correctly except for the Route:

@cedar715 : Could you please share code from which you're trying to create route? And what does your current route look like? Looks like a case of mis-matching apiVersions.

[cedar715]

        final RouteList routes = openShiftClient.routes().inNamespace(namespace).list()

        final List<Route> routeList = routes.getItems()
        final Route existingRoute = routeList.find {
            it.metadata?.name == routeName
        }

        final Route enrichedRoute = enrichTLSConfig(routeFolderPath, route)
        ScalableResource<Route, DoneableRoute> routeOpr = openShiftClient.routes().inNamespace(namespace).withName(routeName) as ScalableResource

        if (existingRoute) {
            final Boolean isDeleted = routeOpr.delete()
            log.info("Deleted route $routeName? :: $isDeleted")
            if (!isDeleted) {
                log.error("Route exists with the name $routeName and could NOT be deleted, terminating!")
                throw new KubeClientException("Route exists with the name $routeName and could NOT be deleted!");
            }
        }
        Route result = routeOpr.createOrReplace(enrichedRoute) as Route
        log.info("Created route: $route")

We don't specify apiVersion in the manifests; its delegated to Fabric8 to determine the apt version based on the cluster version.

[cedar715]

final VersionInfo versionInfo = namespaceOcpClient.version
final String apiVersionToUse = openshiftVersion?.startsWith('3.7') ? 'v1' : 'route.openshift.io/v1'

Got resolved when we explicitly set the version.
