But in the AttachmentsFieldsForVolume struct, it declares type for InstanceId to be int

// AttachmentsFieldsForVolume defines model for Attachments_Fields_for_Volume.
type AttachmentsFieldsForVolume struct {
    Device     *string `json:"device,omitempty"`
    Id         *int    `json:"id,omitempty"`
    InstanceId *int    `json:"instance_id,omitempty"`     <--- Look at this
    Protected  *bool   `json:"protected,omitempty"`
    Status     *string `json:"status,omitempty"`
