It seems you are using a very old version of airflow helm chart, so it's better to upgrade it to a newer version.

For your problem, it says that chmod doesn't exist in your values file, and where it's a simple image used to execute some basic commands, I think you can use any linux image (alpine for example). So to solve the issue, you need to add this to your values.yml file:

chmod:
  image: alpine
