Hey @RajatSharan2505 I faced the same problem. I filled in the “Callback URL” field from the app’s GitHub page and after that everything was ok.

Dear all,  
I was confronted to a similar issue also . **When the authorization tab is selected inside the Oauth folder** , I have the same error `Error: [Object Object]`(I can be generalized to a folder inside a collection). A workaround is to set up the Oauth 2.0 authorization directly in the request which is added to a collection or a folder. _ **For instance, use the same steps in the challenge not on the folder Oauth but directly on the GET github request** _. It works for me !The same outcome is reached.

I also had this error - and it was “fixed” by switching my Callback URL from [http://localhost:3000](http://localhost:3000) to Postman’s [https://oauth.pstmn.io/v1/callback](https://oauth.pstmn.io/v1/callback) (both are permitted by my Azure AD AppReg. The Error message then switched to “Error: invalid\_resource” ; I was using the wrong resource ID for the environment (oops).
