Error 401 while requesting prediction outputs from seldon server

[TechDevCode]

Hi,
I am trying to run examples at following links on my bare metal cluster with 1 physical node as master and other as worker.
https://github.com/SeldonIO/seldon-core/blob/master/notebooks/kubectl_demo_gcp.ipynb
and
https://github.com/SeldonIO/seldon-core/blob/master/examples/models/keras_mnist/README.md

But when I request prediction result from deployed model. I get following error
{'path': '/oauth/token', 'message': 'Bad credentials', 'timestamp': 1521527066875, 'status': 401, 'error': 'Unauthorized'}

This looks like your oauth key/secret is incorrect. Are you sure it matches what you specify in your seldondeployment ?

In https://github.com/SeldonIO/seldon-core/tree/master/examples/models/keras_mnist example I have deployed model using provided "keras_mnist_deployment.json" https://github.com/SeldonIO/seldon-core/blob/master/examples/models/keras_mnist/keras_mnist_deployment.json file. While querying prediction results I have used key as "oauth-key" and secret as "oauth-secret" mentioned in provided keras_mnist_deployment.json file.
Another detail is that I am deploying model in bare-metal cluster, so I have not used load balancer. I have used NodePort. But in the case of NodePort ExternalIP is shown as none instead of nodes for seldon-apiserver as shown below

kubectl get svc -n seldon
NAME               TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)                         AGE
redis              ClusterIP   10.107.221.86   <none>        6379/TCP                        2d
seldon-apiserver   NodePort    10.96.47.170    <none>        8080:30492/TCP,5000:32232/TCP   2d
