This is the second time I have been working on a relatively complex Dynamo graph and it just stops running. Closing and reopening Revit does not help. All my nodes show “null” even though the graph shows “Run completed.” Last time, I had to rewrite the entire thing from scratch. Any ideas on how to get this working again?

Usually there is an invalidated Dynamo node somewhere in there. Locating it can be nearly impossible without using a text editor.

Post your graph so we can review.

I will likely need to delete this attachment after this issue is resolved as this is an in house document that is not allowed to be distributed.

If you check that text file there is a directory path node with a ‘hint’ that is currently `null`. Try changing that to the path (literally the value directly below it) in your text editor, saving it again as a .dyn, and see if that resolves the issue.

That did the trick! Thank you!
