Here are the detailed error messages:
AIL: TestTranslate/authn-single-route-single-match-to-xds| (293.93s) translate_test.go:321: Error Trace: /home/nino/ronniegateway/internal/cmd/egctl/translate_test.go:321 Error: Received unexpected error: failed to translate xds ir for key envoy-gateway-system/eg value &{AccessLog:0xc0000e1ea0 Tracing:<nil> HTTP:[0xc00051e800] TCP:[] UDP:[] EnvoyPatchPolicies:[]}, error:validation failed for xds resource cluster_name:"envoy-gateway-system/backend/rule/0/match/0-www.example.com" endpoints:{locality:{} lb_endpoints:{endpoint:{address:{socket_address:{port_value:3000}}} load_balancing_weight:{value:1}} load_balancing_weight:{value:1}}, err:invalid ClusterLoadAssignment.Endpoints[0]: embedded message failed validation | caused by: invalid LocalityLbEndpoints.LbEndpoints[0]: embedded message failed validation | caused by: invalid LbEndpoint.Endpoint: embedded message failed validation | caused by: invalid Endpoint.Address: embedded message failed validation | caused by: invalid Address.SocketAddress: embedded message failed validation | caused by: invalid SocketAddress.Address: value length must be at least 1 runes

What issue is being seen? Describe what should be happening instead of
the bug, for example: Envoy should not crash, the expected value isn't
returned, etc.

Repro steps:
Add following code to 'internal/xds/types/resourceversiontable.go', then run 'internal/cmd/egctl/translate_test.go'.
case resourcev3.EndpointType: // TBD - ValidateAll() breaks existing test internal/cmd/egctl/translate_test // authn-single-route-single-match-to-xds.endpoint expects address for socketAddress field, but this field currently only has port, does not have address if resourceOfType, ok := xdsResource.(*endpointv3.ClusterLoadAssignment); ok { if err := resourceOfType.ValidateAll(); err != nil { return fmt.Errorf("validation failed for xds resource %+v, err:%v", xdsResource, err) } } else { return fmt.Errorf("failed to cast xds resource %+v to ClusterLoadAssignment type", xdsResource) }

Include sample requests, environment, etc. All data and inputs
required to reproduce the bug.

Note: If there are privacy concerns, sanitize the data prior to
sharing.

Environment:

Include the environment like gateway version, envoy version and so on.

Logs:

Include the access logs and the Envoy logs.
