We are trying to call oic rest webservice enabled Oauth 2.0 from from fusion vbs. We came to know that we can use "Oauth 2.0 Client Credentials" and to setup this we have to select "Local Server Defination" and we also need to setup "Backend" in the fusion under "Manage Backend for Visual Builder" and provide the same extension and backend details. We setup this as per the doc but while calling the api from preview or live we are getting below error.
