OSS Grafana OnCall doesnt pick settings from ENV

[Mdumala]

What went wrong?

What happened:

• After configure entire flow on grafana OSS i run a prepared alert with notification via email
• But in grafana oncall celery i can see :
  oncall 2024-10-31 12:57:01,043 source=engine:celery worker=ForkPoolWorker-2 task_id=03b10dad-0318-47a2-b4d2-6fd109fd3765 task_name=apps.email.tasks.notify_user_async name=apps.email.tasks level=ERROR Error ││ while sending email: empty EMAIL_HOST env variable
• If i put these configuration direct to Value it works perfectly -> which clearly tell us that parameter from Value work but not from ENV
• It looks like it doesnt pick values from ENV column

What did you expect to happen:

• That values passed through ENV will be take by Grafana On Call

How do we reproduce it?

1. Configure smtp properties inside helm chart to Grafana OnCall
2. Verify that these parameters are visible on OnCall->Settings->Env Variables
3. Try to send demo alerts to configured user with rights email
4. Email reach its recipient
