Lock Cognitive Services SDK to 1.9.1

[compulim]

Screenshot

When using Cognitive Services SDK 1.10.0 with Web Chat NPM, we are seeing:

Version

master of now.

Describe the bug

When pairing Cognitive Services SDK 1.10.0 with Direct Line Speech SDK, it failed on this line:

class ConversationImpl extends Conversation {
  ...
}

The problem is Conversation is undefined, causing an error "super expression must either be null or a function".

Translate to human:

const Conversation = undefined; // or 123, 'abc', true, {}, []

class ConversationImpl extends Conversation {
   ...
}

Seems related to microsoft/cognitive-services-speech-sdk-js#155.

Steps to reproduce

1. npm install botframework-directlinespeech on a NPM project
2. Verify node_modules/microsoft-cognitiveservices-speech-sdk to be 1.9.1

Expected behavior

Direct Line Speech SDK should work with npm install. Instead, it bring down 1.10.0 which is not compatible with Direct Line Speech SDK.
