  • Added support for setting 'profile' as an identity attribute from cognito federation.
  • Fix syntax error introduced in 4.4.0 QNAPin and QNAPinNoConfirm bots that prevents updates from succeeding.

[4.3.2]

  • Bug fixes for Kendra FAQ integration
  • Support lengthy answer definition for Kendra FAQ
  • Check of FAQ deletion in Kendra when FAQ content is being resynced
  • Support multiple responses when using Test in content designer with Kendra FAQ enabled
  • Fix for exception - "Cannot convert undefined or null to object" when Session Attributes are no provided during Lex input. aws-solutions#229
  • Package version updates to address current github dependabot alerts

[4.3.0]

  • New Connect Wizard available in the Content Designer UI to assist integration with a Connect Contact Flow.
  • New 4-node Elasticsearch domain support for improved fault tolerance in deployment template.
  • Elicit Response bot support for confirmation responses using phone keypad 1 = yes 2 = no.
  • Security improvements in API Gateway.
  • ID token values removed from session event after validation and redacted from logging.
  • Setting to limit the number of Kendra fallback search results.
  • Setting to enable signed URLs for S3 documents in Kendra search results.

[4.2.4]

  • Add CONNECT_IGNORE_WORDS to settings which allows single character words to be ignored during input to QnABot via Connect. Default is empty string but can be set to an array such as "a,e" such that single character inputTranscript uses the Connect Error branch in Get customer input.
  • Display Kendra document names as the URL and add ability to generate Signed S3 URLs for Kendra document integration. Uses new setting named ALT_SEARCH_KENDRA_S3_SIGNED_URLS. Set this to true to convert Kendra based S3 document URLs to signed urls allowing access.
  • Expose session attributes in the res object as an object such that they are usable in Kibana UI.
  • Fix to ensure a "Test" invocation, when using a topic, always uses ElasticSearch to perform the query.

[4.2.2]

  • Fix KendraFallback Lambda Function lodash dependency

[4.2.1]

  • Return Error if Lex inputTranscript is an empty string or not present. Processing an empty inputTranscript produces other downstream failure.

[4.2.0]

  • New Kendra FAQ support (Beta version) using the setting KENDRA_FAQ_INDEX. New menu item in Designer UI to export Questions as a Kendra FAQ. See revised Blog Post for details.
  • New GetSessionAttribute Handlebars helper to obtain session attribute. Works similar to lodash get(). Will not through exception and will return a default value.
  • Enhanced handlebars to support string concatenation including handlevar 'variables' like Session Attributes and UserInfo, etc. Use case, e.g. to build a url containing a users email, eg a google calendar URL. Example of syntax now supported - in this case to dynamically build a personalized URL based on user info. {{setSessionAttr 'link' 'https://calendar.google.com/calendar/embed?src=' UserInfo.Email '&ctz=America%2FNew_York'}}
  • Moved 'previous' and 'navigation' session attributes under a new 'qnabotcontext' session attribute so that Connect (and other) clients have fewer session attributes to preserve.
  • Allows Chaining rule Lambda function to return a modified session object in addition to the string for chaining.
  • Allows Chaining of up to 10 documents. Each document's Lambda hooks will also be invoked in sequence if defined.
  • Added a new Repeat QID in the QNAUtility example package. Allows QnABot to easily repeat the last answer.
  • Allow the chaining rule to specify a specific QID rather than an answer. A QID can be specified in the chaining rule by using string such as QID:: e.g. QID::Admin.001. Note, the new QID:: syntax can also be used from the webUI, say as button values if/when you prefer to target a specific QID (exact query) rather than rely on question matching.
  • Fixed a defect to allow conditional chaining to be invoked after an elicit response bot failure.
  • Upgrades to and installs ElasticSearch 7.7.

[4.1.0]

  • Install / Upgrade now supports the option to configure S3 Buckets and Elastic Search cluster using encryption at rest
  • Install / Upgrade now supports the option to require Cognito based user authorization to access the built-in full screen web UI (Public/Private parameter in template) - Public is the default
  • Added two settings parameters to enforce user identity verification check, so that bot can be secured for use by authenticated users only
    • ENFORCE_VERIFIED_IDENTITY. Default is false. Set to true to make QnABot require verified identity from client
    • NO_VERIFIED_IDENTITY_QUESTION. The default is "no_verified_identity". If user identity cannot be verified, replace question string with this. If not verified, the system will respond to user's question with the result of searching for NO_VERIFIED_IDENTITY_QUESTION. This allows a customizable message which informs the user that they must log in. A default question with qid "no_verified_identity" is included in QNAUtility example package.
  • Enhanced Kendra fallback integration to use a specific answer if there is a best answer available and bold face highlighted words from Kendra response
  • Added Comprehend sentiment analysis to all utterances and text captured by the QNAFreeText elicit response bot
  • Enhanced Kibana dashboard to identify Lex client channels - Connect, Web, SMS
  • Improved internal use of Booleans from settings configuration
  • Enhanced Connect integration
    • Added session attribute named "qnabot_qid" that holds the matching question id found in elastic search
    • Added session attribute "qnabot_gotanswer" that holds boolean true/fale if an answer was fround
    • Encapsulating all Kendra and Elicit Response Bot session attributes into a single "qnabotcontext" attribute making it easier to store and reset in Connect contact flow
  • Added new QNAYesNoExit elicit response bot which allows a user to exit the YesNoExit question using "exit", "bye", "quit", "admin", "rep","representative","stop", "help", "bye", "goodbye" which sets the Yes_No_Exit slot value / session attribute to "Exit".
  • Update to 0.17.0 of embedded lex-web-ui
