I was getting this error with several workstations, for a few days, til it decided to work yesterday.

Failed to process action: Object reference not set to an instance of an object.

I could not pinpoint a consistant condition for all the workstations. I was thinking that they were all logged out when it refreshed, but the error also appeared in their event viewer on their local computer. Then voila, they started running the bundle, although once again, not consistantly. Some yesterday, some today.

What does this error mean. How can I interepret these errors better. Thanks.
