2021/11/19 - Amazon Lex Runtime V2 - 3 updated api methods
Changes Updates API to latest version.
{'sessionState': {'dialogAction': {'slotElicitationStyle': 'Default | '
'SpellByLetter | '
'SpellByWord'}}}
Returns session information for a specified bot, alias, and user.
For example, you can use this operation to retrieve session information for a user that has left a long-running session in use.
If the bot, alias, or session identifier doesn't exist, Amazon Lex V2 returns a BadRequestException . If the locale doesn't exist or is not enabled for the alias, you receive a BadRequestException .

Sends user input to Amazon Lex V2. Client applications use this API to send requests to Amazon Lex V2 at runtime. Amazon Lex V2 then interprets the user input using the machine learning model that it build for the bot.
In response, Amazon Lex V2 returns the next message to convey to the user and an optional response card to display.
If the optional post-fulfillment response is specified, the messages are returned as follows. For more information, see PostFulfillmentStatusSpecification .
Success message - Returned if the Lambda function completes successfully and the intent state is fulfilled or ready fulfillment if the message is present.
Failed message - The failed message is returned if the Lambda function throws an exception or if the Lambda function returns a failed intent state without a message.
Timeout message - If you don't configure a timeout message and a timeout, and the Lambda function doesn't return within 30 seconds, the timeout message is returned. If you configure a timeout, the timeout message is returned when the period times out.

The value that Amazon Lex V2 determines for the slot. The actual value depends on the setting of the value selection strategy for the bot. You can choose to use the value entered by the user, or you can have Amazon Lex V2 choose the first value in the resolvedValues list.
resolvedValues (list) --
A list of additional values that have been recognized for the slot.
(string) --
