Unable to specify a non-latest jetstream version when configuring an EventBus

[smgtx]

As the title states, I am unable to specify a non-latest jetstream version when configuring an EventBus.

Tested with argo-events 1.7.3, and deployed using argo-events helm chart 2.0.6.

I am getting the following errors from the argo-events controller:
{"level":"error","ts":1668552858.8801756,"logger":"argo-events.eventbus-controller","caller":"eventbus/controller.go:56","msg":"reconcile error","namespace":"argo","eventbus":"default","error":"failed to get jetstream version, err: unsupported version \"2.8.1\", supported versions: \"latest\"","stacktrace":"github.com/argoproj/argo-events/controllers/eventbus.(*reconciler).Reconcile\n\t/home/runner/work/argo-events/argo-events/controllers/eventbus/controller.go:56\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).Reconcile\n\t/home/runner/go/pkg/mod/sigs.k8s.io/[email protected]/pkg/internal/controller/controller.go:114\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).reconcileHandler\n\t/home/runner/go/pkg/mod/sigs.k8s.io/[email protected]/pkg/internal/controller/controller.go:311\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).processNextWorkItem\n\t/home/runner/go/pkg/mod/sigs.k8s.io/[email protected]/pkg/internal/controller/controller.go:266\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).Start.func2.2\n\t/home/runner/go/pkg/mod/sigs.k8s.io/[email protected]/pkg/internal/controller/controller.go:227"}

and from the EventBus

kind: EventBus
metadata:
  name: default
spec:
  jetstream:
    version: 2.8.1

failed to get jetstream version, err: unsupported version "2.8.1", supported versions: "latest"

This error makes sense in the context of the generated yaml:

apiVersion: v1
kind: ConfigMap
metadata:
  name: argo-events-controller-manager
  labels:
    helm.sh/chart: argo-events-2.0.6
    app.kubernetes.io/name: argo-events-controller-manager

          metricsExporterImage: natsio/prometheus-nats-exporter:latest

          max_memory_store: -1

        versions:

          configReloaderImage: natsio/nats-server-config-reloader:latest
          startCommand: /nats-server

I expected there to be more supported versions in the controller-config.yaml section.

For reference, these are the values I am specifying for my helm chart:

        image: 
          tag: v1.7.3
          repository: {internal-registry}/mirror/quay.io/argoproj/argo-events
      webhook:
        serviceAccount:
          name: argo-events-webhook-sa
      controller:
        serviceAccount:
          name: argo-events-sa
      config:
        jetstream:
          versions:
            - version: "2.8.1"
              configReloaderImage: "{internal-registry}/mirror/natsio/nats-server-config-reloader:0.7.4"
              metricsExporterImage: "{internal-registry}/mirror/natsio/prometheus-nats-exporter:0.10.1"
              natsImage: "{internal-registry}/mirror/nats:2.8.1"
              startCommand: "/nats-server"

I would appreciate any guidance on working through this issue.

If you use helm, you can override the versions and provide your own in https://github.com/argoproj/argo-helm/blob/main/charts/argo-events/values.yaml#L70 . I tried that, it works.
