Connect REST with oAuth 2.0 with authorization code - could not acquire fresh access token
I am working on Connecting to a REST service which have oAuth 2.0 with Authorization code. so i created a REST service and oAuth 2.0 client registration in Pega and i tested with Postman. Basically i tried grant types with authorization code, client credentials and password credentials in Postman. Everything worked fine. I created an authentication profile with authorization code grant type and called it in a Connect-REST rule. But when I tried to call the connect rest rule with in an activity, i am getting 'could not acquire fresh access token' error. i am getting same error when i used connect rest rule in datapage. Same Connect REST rules works fine with client credentials and password credentials grant types.

@vinay kumar karumanchi Only i got the logs which i have attached with log_error.jpg. Apart from that there no logs. service is simple where i will pass EMPID in the below service URL, service will look up the employee data table and send the employee details as response. (https://******************/prweb/api/OAuthSendEmp/v1/employee/{EMPID}). As i mentioned in response to Aneesha below, i was able to get the response when i hit the service with Swagger in OpenAPI tab of the service. I am facing problem only when i created connect rest rule and try to use in Activity or Datapage.

@SubhashK7107 Have you configured service package authentication method as OAUTH. That can help

@AneeshaG Yes the method is OAuth in service. Actually I opened that service and tested that service from Swagger under OpenAPI tab. First i clicked on Authorize button, gave client credentials and submitted. It opened Pega login screen, i logged in with SSO and It was authorized. Then i gave the parameters for service and executed and i got the response from the service. I am facing this problem only when i call from Activity or Datapage.

@AneeshaG @vinay kumar karumanchi Is there any pre requisites i should do before calling the Connect REST rule? Both in Postman and Swagger, there was step to get the token to redirect URL by logging into Pega and token was retrieved from that URL. While calling the Connect REST from activity or datapage, i don't know how the redirect URL receives the token.
