Not able to connect to action server in Kubernetes cluster

Hi, I am using helm chart but getting below error for rasa oss pod and it is not executing custom action

Error in logs Failed to execute custom action 'validate_phone_form' because no endpoint is configured to run this custom action.

I dont see any error on action server pod.

I also tried with endpoint entry in rasa-valies.yaml for rasa-action-server but it didn’t help, getting same error

  endpoints:
    ## Fetch the model from your own HTTP server
    ## See: https://rasa.com/docs/rasa/model-storage#load-model-from-server
    action_endpoint:
      url: "http:/localhost:5055/webhook"
