I have an approval workflow using ASPX forms for approval.

When I use try to execute the proper action after submitting the form I receive the following error.

24129 A database error occurred : Procedure or function 'kActionActInstRightsGetAll' expects parameter '@ActionerName', which was not supplied

This during execution of the method

connection.OpenWorklistItem(SerialNumber);

Seems like the parameters aren't up to date. Is there anyone who has an idea to update it? I tried to update Design Templates in my workflow already.
