I have followed the instructions [here](https://serverless.com/framework/docs/providers/kubeless/guide/quick-start/) to create a Python function on my [kubernetes cluster](https://mindmajix.com/kubernetes-training) with the serverless framework & kubeless

I can deploy the function fine:

```auto
$ serverless deploy

```

But if I make a change to the Python code and try to re-deploy:

```auto
$ serverless deploy
...

Serverless: Excluding development dependencies...

  Error --------------------------------------------------

  Found errors while deploying the given functions:
Error: Unable to update the function hello2. Received:
  Code: 422
  Message: functions.k8s.io "hello2" is invalid: metadata.resourceVersion: Invalid value: 0x0: must be specified for an update

```

Thanks,
