Timeout Issue at kale-marshal-volume Stage

[yongyct]

I was going through this example of using kubeflow-kale with the titanic-ml example: https://medium.com/kubeflow/an-end-to-end-ml-workflow-from-notebook-to-kubeflow-pipelines-with-minikf-kale-72244d245d53

notebook image = gcr.io/arrikto/jupyter-kale:v0.5.0-47-g2427cc9 titanic-ml example = https://github.com/kubeflow-kale/examples/tree/master/titanic-ml-dataset

All works fine, until I clicked on "Compile and Run" to translate the notebook into a kubeflow pipeline and run it. However, during the run process, there exists this one stage "kale-marshal-volume" which keeps showing this error: This step is in Error state with this message: Timeout: request did not complete within requested timeout.

I'm running this in a kubeflow v1.2 installed within a GKE cluster v1.19.
