Last updated 3 months ago

When using asynchronous message processing, exceptions thrown from the message handler are silently absorbed by the AMPS Python client by default. The AMPS Python client allows you to register an exception listener to detect and respond to these exceptions. When an exception listener is registered, AMPS will call the exception listener with the exception.

See for details.
