Is there an existing issue for this?

Current Behavior

I deploy the KIC with the Kubernetes Gateway Operator. Using the example configuration from the documentation with

• kong/kubernetes-ingress-controller:3.3.1 and
• kong/kong:3.8.0

When I try to create a KongConsumer resource, e.g.:

apiVersion: configuration.konghq.com/v1
kind: KongConsumer
metadata:
  name: example-consumer
  namespace: example
  annotations:
    kubernetes.io/ingress.class: "kong"
username: example-consumer
credentials:
- example-basic-auth

The controller fails to sync the config to the data plane with the following error:

2024-09-26 11:46:46.570 
2024-09-26T09:46:46Z    error   Entity tags missing fields  {"name": "", "error": "no name"}

The data plane reports an 400 error:

"POST /config?check_hash=1&flatten_errors=1 HTTP/1.1" 400 1133 "-" "Go-http-client/1.1"

Switching to versions:

• kong/kubernetes-ingress-controller:3.2.4 and
• kong/kong:3.7.1

solves the issue and the KongConsumer is synced.

Expected Behavior

The KongConsumer can be synced without an error.

Steps To Reproduce

1. Install the newest versions of the ingress-controller and kong.
2. Try to create a new `KongConsumer` resource.

Kong Ingress Controller version

3.3.1

Kubernetes version

Server Version: v1.30.4+k3s1

Anything else?

I could not reproduce the issue without the credentials part. The error seems to be triggered by the credentials. Could you please provide the details of your secret example-basic-auth?

I have the same issue and was able to reproduce it with the basic-auth plugin sample data.

Secret config is:

apiVersion: v1
kind: Secret
metadata:
  name: alex-basic-auth
  labels:
    konghq.com/credential: basic-auth
stringData:
  username: alex
  password: secret123

Seeing the same problem here. Using similar config to the sample data. Works fine with older versions.
