OAuth Authentication in Application Composer Webservice Error

Summary:

Hi,

We are trying to setup Oracle Fusion Rest Endpoint(itemsV2) in Application composer and use IDCS OAuth Authentication and running into an error.

User Account with same name as Client Id has been created in Fusion.

Testing in SoapUI:

1.Call Fusion Endpoint with Authentication as OAuth 2.0

2.Click Get Token and Enter Client Id, Client Secret, Access Token URI and Scope

3.Click on Get Access Token

4.Token is generated

5.Call the service(GET Method) with token generated and response is received from itemsV2 endpoint.

Setup on Application Composer

1.Create REST Webservice Endpoint under common setup

2.Choose Authentication as "Call using IDCS OAuth"
