Error endpoints "forward-tg" not found with alb.ingress.kubernetes.io/actions.${action-name}

[manushi-bcsn]

I have added a below annotations in my ingress file.

K8s version: 1.29
ALB controller is installed using helm chart.

alb.ingress.kubernetes.io/actions.forward-tg: |
{"type":"forward","targetGroupARN":"ARN of target group"}

Also I have used it in ingress spec.
spec:
rules:

• host: abc.com
  http:
  paths:
  • backend:
    service:
    name: forward-tg
    port:
    name: use-annotation
    path: /bmw
    pathType: Prefix

But it is showing error like as below:

error: forward-tg:use-annotation (<error: endpoints "forward-tg" not found>)

Just to add ALB and my EC2 both are in same VPC and also EC2 is in public subnet.
I have checked to add rule manually in ALB and it is working properly.

I don't know what's the issue with ingress that it could not find my target group ARN.

Can anyone please help me with this?

@manushi-bcsn Can you share your full manifest again? It looks like a formatting error.
I tried creating an ingress using following manifest and it worked for me.

# Ingress
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  namespace: xxx
  name: ig-xxx
  annotations:
    alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 443}]'
    alb.ingress.kubernetes.io/actions.forward-tg: |
      {"type":"forward","targetGroupARN": "arn:aws:elasticloadbalancing:us-east-1:xxxxxxxxx:targetgroup/dssdde/xxxx"}
spec:
  ingressClassName: alb
  rules:
    - host: abc.com
    - http:
        paths:
          - path: /bmw
            pathType: Prefix
            backend:
              service:
                name: forward-tg
                port:
                  name: use-annotation

@shraddhabang

Thanks for the quick reply.
I'll try in my newly created cluster and if it's still not work then I'll let you know.
I found out that something is fishy in our cluster.
