Error while Approving the human Task

Question

Hello Experts,
I’m working for a system integration IDM (Identity and Access Management) project wherein we have integrated Oracle SOA suite 11g with OIM (oracle identity manager 11g) to provide approval workflows. The approval requests are raised in OIM and OIM invokes a SOA composite to route the approval to various human actors.
I have created a SOA composite where in the 1st level approver is manager and second level approval is a role . When i raise the request the task is assigned to the manager and manager approves it . Then the task is assigned to the Role . However the issue is , when any member of the Role tries to approve the task , the below error is thrown . Please note he is able to reject the request though , only in case of approving i see the below error .
Though it shows in the logs as warning but on the approval UI (Oracle Identity Manager UI ) , it throws an error . ie ."An Error Occured "
Any clues Pls !
