My current project involves creating a chat bot using the Microsoft Bot Framework and SDK in TypeScript. I am working on implementing user authentication for the bot to interact with Azure DevOps on behalf of users. While testing authentication in Azure Portal is successful, I encounter a 401 error when trying to authenticate the user in Teams and access the Azure DevOps APIs.
As someone new to the Microsoft stack, I have been following a guide available at here for reference.
The process involved setting up a Bot Channels Registration with an associated App Registration containing necessary credentials stored as environment variables in the Azure Portal. Additionally, I created another App Registration for Azure DevOps authorization with proper API permissions granted.
Configuring OAuth Connection Settings within the Bot Channels Registration was done next, ensuring correct setup and successful connection tests before proceeding with code implementation.
When it comes to writing the code itself, my application is built using TypeScript with Node.js and Restify. The bot code extends ActivityHandler with various functions to handle different events including token response and activity types.
Adding OAuth prompts and waterfall dialogs is essential for guiding users through the login process seamlessly before interacting with Azure DevOps services using the provided bearer token auth handler.
However, encountering a recurring 401 error during attempts to access Azure resources with the logged-in user's credentials has left me puzzled. Debugging efforts reveal specific details about the unauthorized request exception encountered.
This detailed overview summarizes my troubleshooting journey so far. Any assistance or guidance on resolving this issue effectively would be greatly appreciated!
