dahua_event_received events coming in inconsistent format

[jakon89]

I have an automation setup that listens for dahua_event_received events.

So far, all dahua_event_received events except one came with the correct format. However, there was a single event where trigger.event.data.data was sent as a string (JSON), and my automation could not process it - it expected the object to be sent, not a "flat" string. This is strange - both events are posted below.

Below I am pasting two automation traces: first one where valid event was received and the second one with malformed data.

The correct event that is usually fired by this dahua integration:

this:
  entity_id: automation.notify_about_irv_rule
