deephaven.dherror

This module defines a custom exception for the Deephaven Python Integration Package.

The custom exception is named DHError. It encapsulates exceptions thrown by the Deephaven engine and the Python/Java integration layer and provides 3 convenient properties: root_cause, compact_traceback, and traceback for easy debugging.

It is a good practice for Python code to catch this exception and handle it appropriately.
