[Metal] CreateMetalGatewayExecute fails with "data failed to match schemas in oneOf(FindMetalGatewayById200Response)"

[fmontorsi-equinix]

I noticed creating programmatically a Metal Gateway always fail:

import (
	"context"
	"encoding/json"
	"errors"
	"fmt"
	"io"
	"strings"

	"github.com/equinix/equinix-sdk-go/services/metalv1"
)

...
	// create a metal gateway
	mgwReqInput := metalv1.NewMetalGatewayCreateInput(   .... some VLAN ID already deployed in the metro...  )
	mgwReqInput.SetIpReservationId( ... some reservation ID... )
	mgwReqAPI := client.MetalGatewaysApi.CreateMetalGateway(ctx, projectID)
	mgqReq := mgwReqAPI.CreateMetalGatewayRequest(metalv1.CreateMetalGatewayRequest{MetalGatewayCreateInput: mgwReqInput})

	_, mgwResp, mgwErr := client.MetalGatewaysApi.CreateMetalGatewayExecute(mgqReq)
	defer mgwResp.Body.Close()
        if mgwErr != nil {
		/* this error is always non-nil: and contains "data failed to match schemas in oneOf(FindMetalGatewayById200Response)" */
	}

...

Is this a known bug?
The DeleteMetalGatewayExecute API fails in the same way...

This is a known bug, but the previous issue for it was closed for some reason. That issue has an example of how to work around the bug: #64 (comment)
