PeopleSoft Approval Workflow Engine -- Error on DoSubmit

I am using the code below and getting Error

Unable to DoSubmit on the ApprovalManager.Error - %1: bind number %2 greater than number of input parameters. (0,0)

Appreciate any help in resolving this error.

try

     If &c_aweLaunchManager.hasAppDef Then
        If &c_aweLaunchManager.submitEnabled Then
           &c_aweLaunchManager.DoSubmit();
        Else
           If &c_aweLaunchManager.hasEndedAppInst Then
              &c_aweLaunchManager.TerminateRunningProcess();
              &c_aweLaunchManager.DoResubmit();
           Else
