What happened and how to reproduce it?

I have a helm chart config where i set

executor: CeleryExecutor,harvest_exec:KubernetesExecutor

This is causing an error when deploying

one or more objects failed to apply, reason: Deployment.apps "airflow-scheduler" is invalid: metadata.labels: Invalid value: "CeleryExecutor-harvest_exec:KubernetesExecutor": a valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyValue',  or 'my_value',  or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?') (retried 5 times).

Aliases are well-documented in the documentation, but it seems the helm-chart still does not support them.

What you think should happen instead?

Helm chart should properly parse, an executor definition with aliases
