Bot Authentication Issue

Question

We have a Node.js Bot Framework bot hosted on Azure App Service (Linux) and connected to an Azure Bot resource for Web Chat. The error indicates our token request is being directed to the “Bot Framework” directory instead of our tenant, despite providing TenantId and setting MicrosoftAppType=SingleTenant.

Repro steps

1. Open Azure Bot - Test in Web Chat.

Send any message (e.g., “hello”).

The bot logs onTurnError with AADSTS700016 and no reply appears in Web Chat.

Hello Dhruvi Kapatel,

AADSTS700016: Application with identifier '717c2fdc-7edb-41eb-bdbd-6a392a378f37' was not found in the directory 'Bot Framework'. You may have sent your authentication request to the wrong tenant.

This typically occurs when the Azure Bot resource is not properly linked to the App Registration in your own tenant, and the token request is falling back to the default Bot Framework tenant instead.

This error happens because the bot’s AppId is not correctly resolved within your tenant, causing it to try authenticating against the Bot Framework tenant instead. Double-check your App Registration, Bot resource configuration, and App Service environment variables to ensure all IDs and secrets align with your tenant.
