Finding QnAKnowledgebaseId and QnASubscriptionKey to configure the new Azure Bot Service
Bot Service went through an overhaul again; the configuration to connect your Bot Service to QnAMaker is different now. I am not sure for how long the information here will stay relevant but it is how you configure your Azure Bot Service to talk to QnAMaker.ai at the time of writing this post.
Here's where you can find them:
Go to https://qnamaker.ai/Home/MyServices click on your bot's "View Code"
Hope that helps.
