What can be done to make sure all errors are caught within an assembly?

In an IBM API Connect assembly, the most robust method to ensure all errors are handled is to implement a default catch block. A catch block can be configured to handle specific error names (cases). However, by configuring a catch block without specifying any particular cases, it functions as a "catch-all" or default error handler. This ensures that any error occurring during the assembly execution that is not caught by a more specific catch block will be processed by this default catch, preventing unhandled exceptions and providing a consistent error management strategy.

1. IBM API Connect v10.x Documentation

"Handling errors in the assembly": This official documentation explicitly states

"If you want to handle all errors in the same way

you can configure a single catch that does not specify any particular cases. This catch then acts as a default error handler." This directly supports the use of a default catch to handle all errors.

2. IBM API Connect v10.x Documentation

"Catch": This page details the configuration of the catch scope. It explains that a catch without any specified cases will handle any error that is thrown

confirming its role as a default handler. It contrasts this with specific cases that match on error.name.
