Data related to an event handling failure.

The available fields are:

  • :application - the associated Commanded.Application.

  • :handler_name - the name of the event handler.

  • :handler_state - optional event handler state.

  • :context - a map that is passed between each failure. Use it to store any transient state between failures. As an example it could be used to count error failures and stop or skip the problematic event after too many.
