Image V2: cannot unmarshal string into Go struct field .images.tmp.Properties of type map[string]interface {} #3588

Description

@chanchiwai-ray

What happened?

When user provide additional metadata to an image with a key properties, this will cause the unmarshal of Image struct broken.

To reproduce, create an image in glance, and add a property named properties

openstack image set <MY_IMAGE> --properties properties="anything, it can be {'hypervisor_type': 'qemu', 'architecture': 'x86_64'}"

Then, use the sdk to list that image

package main

import (
    "context"

    "github.com/gophercloud/gophercloud/v2"
    "github.com/gophercloud/gophercloud/v2/openstack"
    "github.com/gophercloud/gophercloud/v2/openstack/image/v2/images"
)

func main() {
    ctx := context.Background()

    opts, err := openstack.AuthOptionsFromEnv()
    if err != nil {
        panic(err)
    }

    providerClient, err := openstack.AuthenticatedClient(ctx, opts)
    if err != nil {
        panic(err)
    }

    listOpts := images.ListOpts{
        Name: "<MY_IMAGE>",
    }

    imageClient, err := openstack.NewImageV2(providerClient, gophercloud.EndpointOpts{})
    if err != nil {
        panic(err)
    }

    _, err := images.List(imageClient, listOpts).AllPages(ctx)   # should failed here
    if err != nil {
        panic(err)
    }
}

Useful debugging information to help identify the issue:

openstack image show <MY_IMAGE> --debug

Note the last RESP BODY from the debug output.
