# Custom Llama Stack Exception classes should follow the following schema
|
|
# 1. All classes should inherit from an existing Built-In Exception class: https://docs.python.org/3/library/exceptions.html
|
|
# 2. All classes should have a custom error message with the goal of informing the Llama Stack user specifically
|
|
# 3. All classes should propogate the inherited __init__ function otherwise via 'super().__init__(message)'
