Exception Handling in Event Listeners

[Larapriar]

Is there any way to control exceptions thrown within event listeners?

We’re using events to communicate between modules, but we’re unsure how to properly manage the different types of exceptions that may be thrown by a module.

We’re currently dealing with two types of exceptions:

• Retryable exceptions – should trigger a resubmission.
• Non-retryable exceptions – should mark the event as failed.

We attempted to handle this by creating an aspect that marks the event as failed. However, the only way we found to prevent an exception from being retried was to simulate multiple attempts until the scheduler stops picking up the event—based on resubmission options with a high attempt count. This approach feels quite hacky and not clean.

Additionally, we noticed that unless the exception is rethrown, Modulith marks the event as completed—even if we explicitly marked it as failed. This behavior seems counterintuitive.

Is there anything on the roadmap regarding better exception management for events?
