Error "panic: runtime error: invalid memory address or nil pointer dereference" when Generating manifests with new CR

[elraoustih]

Hi,
I'm using Kubebuilder (for the first time) to create a custom operator in Go. So in my CR i want to include istio HTTPRoute type. Here my CR def :

package v1

import (
	networkingv1alpha3 "istio.io/api/networking/v1alpha3"
	metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
)

type VirtualServiceFragmentSpec struct {
	// INSERT ADDITIONAL STATUS FIELD - define observed state of cluster
	// Important: Run "make" to regenerate code after modifying this file
	HandledRevision string `json:"handledRevision,omitempty"`

	// +kubebuilder:validation:Required
	Target string `json:"name"`

	// +kubebuilder:validation:Required
	Gateways []string `json:"gateways"`

	// +kubebuilder:validation:Required
	Hosts []string `json:"hosts"`

	// +kubebuilder:validation:Optional
	Http *networkingv1alpha3.HTTPRoute `json:"http,omitempty"`
}

When i'm generating manifest with command "make manifest" i have an error like this (the error disappear when i remove the field Http *networkingv1alpha3.HTTPRoute ) :

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x2 addr=0x0 pc=0x10493ff5c]
