Error when creating CRD

Hi, I'm trying to install chart version 0.2.0. As a result I'm getting following error:

Error: CustomResourceDefinition.apiextensions.k8s.io "flinkclusters.flinkoperator.k8s.io" is invalid: [spec.validation.openAPIV3Schema.properties[spec].properties[job].properties[initContainers].items.properties[ports].items.properties[protocol].default: Required value: this property is in x-kubernetes-list-map-keys, so it must have a default or be a required property, spec.validation.openAPIV3Schema.properties[spec].properties[jobManager].properties[initContainers].items.properties[ports].items.properties[protocol].default: Required value: this property is in x-kubernetes-list-map-keys, so it must have a default or be a required property, spec.validation.openAPIV3Schema.properties[spec].properties[jobManager].properties[sidecars].items.properties[ports].items.properties[protocol].default: Required value: this property is in x-kubernetes-list-map-keys, so it must have a default or be a required property, spec.validation.openAPIV3Schema.properties[spec].properties[taskManager].properties[sidecars].items.properties[ports].items.properties[protocol].default: Required value: this property is in x-kubernetes-list-map-keys, so it must have a default or be a required property, spec.validation.openAPIV3Schema.properties[spec].properties[taskManager].properties[initContainers].items.properties[ports].items.properties[protocol].default: Required value: this property is in x-kubernetes-list-map-keys, so it must have a default or be a required property]
