Hello!
I’m having a strange problem that is very simple to explain, but (apparently) very difficult to debug.
I create a new dynamo graph and place the OOTB node “Rail types”. I save the file. I open the same file and suddenly the node has two outputs instead of one. Every time I save and open it again, there is a new output:

This messes up the graphic and from then on I can’t use it.
Has this happened to anyone?
Any suggestions to solve this?
Thanks !
This occurs when you have a conflict with a dependency between Dynamo and Revit or one of the packages which Dynamo loads.
Troubleshooting steps:
- Make sure you have completely updated Revit.
- Make sure the Dynamo packages you’re using are the correct ones for your Dynamo and Revit version.
- If after those two steps it persists, then disable ALL your Revit add-ins and see if it that clears up the issue.
- If so:
- Add the Revit add-ins back in small groups until you find which one is causing the issue. Note that a binary search can help reduce the number of tests here which is good as you will need to restart Revit at each test.
- Once you know which add-in it is, either: leave it disabled, update to the latest build, or inform the provider of the conflict.
- If not:
- Be sure that you have all Revit add-ins disabled. 99% of the situations where this continues my colleagues have found that something was left enabled.
- Next step is to reach out to my colleagues in support, by submitting a ticket at manage.autodesk.com. Be sure to attach your Dynamo log and Revit journal to the case as that will be the first request.
Hi @jacob.small , thank you for the reply.
I’ve been trying to debug this, specially regarding packages and plug-ins and sadly couldn’t solve it. I found a workaround with the data-shapes package, by providing the railing types list as an input.
Thanks anyway!
