I get the following error at a specific activity. In the my workflow the first activity is a custom where I am initializing a few variables. The next activity is a subprocess.

The first activity executes properly. When subrocess starts the following error occurs and then the execution starts from the first activity and this time everything runs smoothly. This happens each time I run the workflow. Is there anything wrong the workflow is designed? Please Help!!
