Unable to elaborate request: Unable to find the service for function "function-name"

[raravena80]

Is this a BUG REPORT or FEATURE REQUEST?:

But

What happened:

Getting the following with K8s v1.18.2 when trying to trigger a function.

time="2020-07-14T22:00:15Z" level=error msg="Unable to elaborate request: Unable to find the service for function my-handler"

My guess is that it can't find the service because there is an API version mismatch.

The service is there in the cluster on the same namespace as the controller

kubectl get svc my-handler
NAME         TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)    AGE
my-handler   ClusterIP   10.105.218.61   <none>        8080/TCP   50m

What you expected to happen:

The function should be trigger by publishing a message to a Kafka topic

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Hi @raravena80. Indeed this is a known issue. Kubeless is not compatible with Kubernetes 1.18 at the moment. See more info here: vmware-archive/kubeless#1130
