exceptions

Custom exceptions for the conversation flow system.

This module defines the exception hierarchy used throughout the flow system for better error handling and debugging. All exceptions inherit from FlowError to provide a common base for flow-related errors.

exception pipecat.flows.exceptions.FlowError

Bases: Exception

Base exception for all flow-related errors.

This is the parent class for all flow system exceptions. Use this for generic flow errors or when a more specific exception doesn’t apply.

exception pipecat.flows.exceptions.FlowInitializationError

Bases: FlowError

Raised when flow initialization fails.

This exception occurs during flow manager setup, typically due to invalid configuration, missing dependencies, or initialization errors.

exception pipecat.flows.exceptions.FlowTransitionError

Bases: FlowError

Raised when a state transition fails.

This exception occurs when transitioning between nodes fails due to invalid node configurations, missing target nodes, or transition errors.

exception pipecat.flows.exceptions.InvalidFunctionError

Bases: FlowError

Raised when an invalid or unavailable function is called.

This exception occurs when attempting to call functions that are not properly registered, have invalid signatures, or cannot be found.

exception pipecat.flows.exceptions.ActionError

Bases: FlowError

Raised when an action execution fails.

This exception occurs during action execution, including built-in actions like TTS or custom actions, due to invalid configuration or execution errors.
