data class InstanceEndpoint(val alternativeEndpoints: String? = null, val enabled: Boolean? = null, val endpoint: String? = null, val type: String? = null, val vpcId: String? = null, val vpcInstanceId: String? = null, val vswitchId: String? = null)
Some old instances have both AnyTunnel and SingleTunnel enabled. When switching from AnyTunnel to SingleTunnel, the endpoints of both are retained. Therefore, one more field is required to store the Endpoint.
