subnets in AZ "" not found

[james beedy]

First time I've seen this http://paste.ubuntu.com/p/CJdjks3b5n/

Ceph was deployed with

$ juju deploy -n 3 ceph-mon --constraints "instance-type=t3.large root-disk=20G spaces=nat"

$ juju deploy -n 3 ceph-osd --storage osd-devices=ebs,32G,2 --storage osd-journals=ebs,8G,1 --constraints "instance-type=t3.large root-disk=20G spaces=nat"

Do you have a constraint on what spaces you want those units deployed to?

The code that is generating that error is:
func findSubnetIDsForAvailabilityZone(zoneName string, subnetsToZones
map[network.Id][]string) ([]string, error) {
        matchingSubnetIDs := set.NewStrings()
        for subnetID, zones := range subnetsToZones {
                zonesSet := set.NewStrings(zones...)
                if zonesSet.Contains(zoneName) {
                        matchingSubnetIDs.Add(string(subnetID))
                }
        }

        if matchingSubnetIDs.IsEmpty() {
                return nil, errors.NotFoundf("subnets in AZ %q", zoneName)
        }

        return matchingSubnetIDs.SortedValues(), nil
}

The zone name seems to come from:
availabilityZone, placementSubnetID, err :=
e.deriveAvailabilityZoneAndSubnetID(ctx, args)
which then has
haveVPCID := isVPCIDSet(e.ecfg().vpcID())
var subnetIDsForZone []string
var subnetErr error
if haveVPCID {
...
} else if args.Constraints.HasSpaces() {
subnetIDsForZone, subnetErr =
findSubnetIDsForAvailabilityZone(availabilityZone, args.SubnetsToZones)

I don't quite see how deriveAvailailabilityZoneAndSubnetId isn't returning
an error if the availabilityZone is the empty string. I do see lines like:
if availabilityZone == "" {
return "", "", errors.NotValidf("availability zone %q", availabilityZone)
}

This does feel like it is some sort of interaction with storage, as I see
these lines:
volumeAttachmentsZone, err := volumeAttachmentsZone(e.ec2, ctx,
args.VolumeAttachments)
if err != nil {
return "", "", errors.Trace(err)
}
placementZone, placementSubnetID, err := e.instancePlacementZone(ctx,
args.Placement, volumeAttachmentsZone)
if err != nil {
return "", "", errors.Trace(err)
}

and given the name of the applications includes "ceph".
