get_session(**kwargs)¶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 .
