I am trying to develop a chat bot using Microsoft bot framework V4 and language as Node.js but don't want to deploy in Azure rather than want to keep it to my local machine.
As I don't want Azure, I am unable to create QnA maker knowledgebase without Azure.
Unfortunately, there is no such way to create a Knowledge Base without creating the QnAMaker resources on Azure. You must first set up a QnA Maker service in Azure before creating a knowledge base. The QnAMaker resource manages the knowledge base content. Without the QnAMaker resource and the authoring and endpoint keys, you cannot use the Azure Cognitive Service or make a call to the knowledge base.
Please refer to the following documentation for more details.
