`cluster.wait_ready()` fails with `'MissingModel' object is not callable`

As part of my automated Codeflare testing, I'm hitting this exception:

This python file is being executed:

    # Create our cluster and submit appwrapper
    cluster = Cluster(ClusterConfiguration(

    # Bring up the cluster
    cluster.up()
    cluster.wait_ready() # <-- this line raises the exception
    cluster.status()
    cluster.details()

    job_def = DDPJobDefinition(name="mnisttest", script="mnist.py", workspace=".", scheduler_args={"requirements": "./requirements.txt"})
    job = job_def.submit(cluster)

The RayCluster Pods are pending because of project-codeflare/multi-cluster-app-dispatcher#512, but codeflare-sdk shouldn't fail because of it:

Here is the state of the AppWrapper (captured manually after the test):
appwrapper.yaml.log

---

• Codeflare SDK is installed from pip (latest version)
  • I'll remove the --quiet flag to capture the exact version being installed
• Codeflare stack is installed from ODH + OpenShift Codeflare operator

seems to be the same issue as #226
