Typically this is caused by an exception in the parameters that you you hand over to the REST activity.
Try adding a log activity before making your REST call, displaying your input parameters - wrapped in try..catch - and showing whatever exception is thrown. That should guide you into the right direction.
Sample causes may include plain syntax errors or trying to call GCV.getNamedPassword() when permissions are not set correctly.
Good luck Wolfgang
