error retrieving network with id %s: %v
Error message
error retrieving network with id %s: %v
What it means
After successfully resolving the subnet, fetching its parent network by NetworkID failed. The GetNetwork call is retried; failure means the network could not be read even though the subnet references it.

Defensive patterns
Strategy: retry
Try / catch
net, err := findNetworkBySubnetID(c, subnetID)
if err != nil {
var gerr gophercloud.ErrUnexpectedResponseCode
if errors.As(err, &gerr) && gerr.Actual == 403 {
return fmt.Errorf("no RBAC access to subnet's network: %w", err)
}
return err
} Prevention
- Set up Neutron RBAC for shared networks accessed cross-project
- Avoid deleting a subnet's parent network out-of-band
- Use subnets whose networks are readable by the cluster's project
When it happens
Trigger: The network referenced by subnet.NetworkID cannot be fetched: 404 (network deleted), 403 (no access), or API error.
Common situations: Subnet's parent network deleted between the two calls; shared-network RBAC denies cross-project network read; Neutron outage.
Understand the failure class
Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
