I'm reading data.coder_workspace_owner.me.email in a template for use in Kubernetes, to derive the user's namespace from their email address. During destroy, the datasource returns default@example.com, so my template breaks. Is there a stable way to access the user's email from within the template?

This is the code I'm using now which doesn't work:

namespace = data.coder_workspace_owner.me.email != "default@example.com" ? replace(split("@", data.coder_workspace_owner.me.email)[0], ".", "-") : "coder"

I added a check for the default value after noticing template push failed validation
