typed-rest-client | Node Rest and Http Clients | REST library

I am trying to create a chat bot using the microsoft botframework and the SDK in typescript. I am trying to have the bot authenticate users and then interact with Azure DevOps on their behalf. However, while I am able to test authentication successfully in Azure portal, when I try to authenticate the user in Teams, the login "succeeds", but the bot returns a 401 error trying to hit the Azure DevOps API's.

I am new to a lot of the microsoft stack, and was following the guide here: https://docs.microsoft.com/en-us/azure/bot-service/bot-builder-authentication?view=azure-bot-service-4.0&tabs=javascript%2Cbot-oauth.

First, I have created my Bot Channels Registration. It has an App Registration associated with it (that was manually created). The appId and secret are set up as environment variables in the App Service on Azure Portal.

Second, I have created another App Registration for my Azure Devops authorization. This app registration has a redirect URI of "https://token.botframework.com/.auth/web/redirect", and has a secret created for it. This app registration also is setup to have the API permissions "user_impersonation" for Azure Devops.

Third, I have gone into my Bot Channels Registration, clicked on the "Settings" blade, and configured an OAuth Connection Setting. This setting has the name "azureDevopsOauth", is setup for an Azure Active Directory V2 service provider, and includes the client id, secret and tenant ID of the app registration I made in the second step. It also has the scope set to "openid".

When I click "Test Connection" at the top of this oauth configuration, everything works fine. I am taken to a success page, and am able to view a token there.

Moving on to the code, I know teams is a bit funky with OAuth. My application is written in typescript using node and restify to handle the server aspect. My bot code, which extends the ActivityHandler, has the usual onMembersAdded, onMessage and onDialog functions. I've also added an onTokenResponseEvent and onUnrecognizedActvityType to handle the token response and invoke activity type.

See the library here https://github.com/Microsoft/azure-pipelines-task-lib/blob/master/node/docs/azure-pipelines-task-lib.md

I'm using this to create a minimal release task, which I can succesfully call into. In this task, I call const myUrl: string = tl.getEndpointUrl('myEndpoint', true); How can I then make a web request using this url?

I've tried import * as rm from 'typed-rest-client/RestClient'; and using the rest client, but when I run this on the Azure devops build agent, I get the output:

##[error]Unhandled: Cannot find module 'typed-rest-client/RestClient'

I want to add some headers to a request using typed-rest-client in Typescript.

I didn't find any documentation so I looked a bit at typed-rest-client source code but I didn't manage to fully understand how it works.

I've tried the following code, but I get the error: "ReferenceError: Headers is not defined". So I don't think I have to create an instance of the class Headers.

I'm very new to Typescript and developing my first Electron based application. The first part is a class that populates a local DB with results from a json web service.

My Classes to get the data are as below, an extended class. Within the getAll, if I console out the body after JSON.parse I can see my results in my console without a problem.

My backend is an ASPNet WebApi2 running under IIS and uses Windows Authentification.

I have 2 clients:

1. WinForms: Passing the credentials is simple. I do the following:
