I am developing Microsoft azure QnA Maker Bot with javascript. I have added questions in knowledge based of qnamaker.io. i have created javascript project with botbuilder and create .bot file for adding services like,

{ "name":"qna-bot-v4", "services": [ { "type":"endpoint", "name":"development", "endpoint":"http://localhost:3978/api/messages", "appId":"", "appPassword":"", "id":"1" }, { "type":"qna", "name":"xxx-test-kb", "kbId":"d7e734bc-6e1b-499c-80bc-42eb6db2fb3d", "hostname":"https://xxx-qna-service.cognitiveservices.azure.com/", "endpointKey": "78511920-63b0-4437-8a7e-9bafbac54ac3", "subscriptionKey":"1c44011f-1da7-4239-bd15-5be74bbfc664", "id":"123" } ], "padlock":"", "version":"2.0" }

I have updated index.js file with botbuilderconfigurations and botbuilder-config and set the path of botfile with .env file. When i run the index.js file with command node index.js then i'm getting following error.

Error reading bot file. please ensure you have valid botFilePath
