Error: json: cannot unmarshal array into Go struct field ConfigMapArgs.configMapGenerator.env of type string

/kind bug

What steps did you take and what happened: In order to use kubeflow metadata component, I was following the instructions given in the documentation, https://www.kubeflow.org/docs/components/metadata/#installing-the-metadata-component.

But I get the following error:

kustomize build overlays/db/
Error: json: cannot unmarshal array into Go struct field ConfigMapArgs.configMapGenerator.env of type string

(Also reported here: #2650) What did you expect to happen: Kustomize to build successfully.

Anything else you would like to add: Kustomize version error #148:

kustomize version 
Version: {Version:unknown GitCommit:$Format:%H$ BuildDate:1970-01-01T00:00:00Z GoOs:linux GoArch:amd64}

Environment:

• Metadata version: Unable to install
• Kubeflow version: 1.0.2
• Minikube version: N/A
• Kubernetes version: (use kubectl version): 1.18.2
• OS (e.g. from /etc/os-release): Ubuntu 18.04
