Hey All,

I’ve opened a script written for Dynamo for Revit 20 **21** , in Revit 20 **23**. I’m getting an error for 2 of the nodes within the “Workspace References” panel stating that the graph depends on a previous version of that package. While I _do_ have the latest version of the package installed, how can I determine within my graph which nodes depend on the old version to be able to fix them?

Thanks,  
Scott

The most simple answer to this is:

Install the IronPython package from the package manager and you will be good to go.
