Postman OAuth 2.0 "request url is empty" error even though successful authentication

I authenticate using OAuth 2.0 authorization code workflow successfully and get redirected back to Postman. Here is more information on the Azure DevOps REST API I am trying to do.

In the console, I get an error: request URL is empty

I do not see the authorization code in the response for me to parse, but if I expand the error message and look in the Request Body > code, my authorization code is there!

I am able to use the authorization code to successfully obtain an Access Token as well.

Steps to reproduce error:

  1. I set all of the values in the OAuth 2.0 form
  2. I click Get New Access Token
  3. I get redirected to my browser to accept
  4. I get a successful authentication & get redirected back to Postman
  5. I get the Authorization code in the request body of a console error (I also get the auth code in the URL after authenticating)

On step #5, I expect to get redirected back to Postman successfully with the authorization code in the body of the message.

EDIT: The solution below works for the Azure API with a scope of https://graph.microsoft.com. If the scope is https://app.vssps.visualstudio.com (which is what I'm using), the solution will not work oddly enough.

Please try my steps to get access token with OAuth 2.0 in Postman.

POST https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token

Callback URL: the Redirect URI in Application > Authentication. It is required. Don't select Authorize using browser.

Auth URL: https://login.microsoftonline.com/{tenant}/oauth2/v2.0/authorize

Access Token URL: https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token

For more information, you could refer to the blog which uses oauth2 v1.0.
