Ah. It was there all the time. That is the portion of the message I was asking for. It is telling you that the error occurred at an Invoke Node within the Vision Processing.vi that was called from Robot Main.vi. The Invoke Node is used to run a published method on a control or object in LV. In this case, it is used to retrieve click information from the picture control and is used for interactive calibration.

It is the box towards the bottom of the while loop labeled Original Image and Get Last Event.

If you do not need the click info, you can delete the Invoke Node. If you want to keep it, we need to figure out why it is returning the error.
