I faced the issue where frigate-notify didn't send the notification when it should have:

Describe the solution you'd like

• Operator must be able to set the required log level supported by zerolog.
• TRACE log level must expose internal frigate-notify structures, payload of events received from Frigate, payload sent towards endpoint of notification system, response of from the notification system.
