Helm Install failing without giving much information about the cause/

I am installing the mist.io chart which has below three chart dependencies

1. mongodb-12.1.19.tg
2. rabbitmq-10.1.5.tgz
3. victoria-metrics-cluster-0.8.24.tgz

However, when I try to install it, I am getting a failure error. the error message is not much help in identifying the issue.

command:

helm install test-staging chart/mist

Output:

Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: error validating "": error validating data: ValidationError(StatefulSet.spec.updateStrategy): invalid type for io.k8s.api.apps.v1.StatefulSetUpdateStrategy: got "string", expected "map"

This might be an issue with Kubernetes api version, where you are using a latest api with old helm chart and chart's values.yaml. Below is an indicative change of the updateStrategy, where it could be changed from:

updateStrategy: RollingUpdate

To:

updateStrategy:
    type: RollingUpdate

This worked for, where in my case I had an old version of mysql helm chart used for Kubernetes version 1.17 and tried to use it with Kubernetes version 1.19.

Please refer the relevant Kubernetes official documentation from here: https://kubernetes.io/docs/tutorials/stateful-application/basic-stateful-set/#updating-statefulsets, before you make your changes.
