You can only use this field in the de-DE, en-AU, en-GB, en-US, es-419, es-ES, es-US, fr-CA, fr-FR, and it-IT locales. In all other locales, the "message" field is null. You should use the "encodedMessage" field instead.

Map of key/value pairs representing session-specific context information.

SessionId => Str

A unique identifier for the session.

Slots => Str

Map of zero or more intent slots Amazon Lex detected from the user input during the conversation.

Amazon Lex creates a resolution list containing likely values for a slot. The value that it returns is determined by the "valueSelectionStrategy" selected when the slot type was created or updated. If "valueSelectionStrategy" is set to "ORIGINAL_VALUE", the value provided by the user is returned, if the user value is similar to the slot values. If "valueSelectionStrategy" is set to "TOP_RESOLUTION" Amazon Lex returns the first value in the resolution list or, if there is no resolution list, null. If you don't specify a "valueSelectionStrategy" the default is "ORIGINAL_VALUE".

SlotToElicit => Str

If the "dialogState" is "ElicitSlot", returns the name of the slot for which Amazon Lex is eliciting a value.
