fernetKey when using airflow as dependency

[RyanQuey]

When running this chart on its own, it worked great for me as expected. However, when I defined it as a dependency in my Chart.yaml, the airflow containers fail to start up correctly, and I get something like this:

It seems to be related to this helm secret yaml file, but beyond that I'm having trouble debugging. I tried specifying different values for fernetKeySecretName and fernetKey in the helm values config, but haven't had any luck getting passed this.

Any suggestions?
