As the bot is working just fine on the emulator locally, the problem seems to be the way you are publishing the bot on Azure. A few troubleshooting steps to follow would be :

• Check if you have configured the "Microsoft AppID" and "Microsoft AppPassword" in the appsettings.json correctly.
• Verify the LuisAPIHostname is set to "westus" in the Azure Portal> Your Resource Group > App service > Configuration
• Double check if the keys are correct in the Azure Portal.
• Verify if you missed any of the steps to deploy the bot on Azure.
