Out-of-order messages are not handled by default. Designers must define out-of-order message handlers at the skill level.

Dialog flow navigation continues with the state referenced in the out-of-order-message action.

Chatbots don't control the user's input and, therefore, cannot prevent users from selecting out-of-scope actions.

Out-of-order messages occur when a user scroll the conversation history displayed in the messenger client and selects that is no longer in scope for the current conversation.

An error handler can be defined as a transition on any dialog flow state in a skill.

The system error handler is called in case of an error when no error handling is defined on the current dialog flow state or as a default transition.

Youcan define a system-wide custom error handler at the digital assistant level.

Implicit error handling is always performed even if there are other error handlers defined in the flow.

An error handler can be defined globally for a skill using thedefaultTransition error transition.
