Dynamo for Revit 2018

Hi All,
I have Revit 2018 on my computer and I installed Dynamo 2.01 .
I can select an element and save the file. but when I try to open it, it shows an error message that the node view does not contain a node match.
what might be the issue. Thank you for your help.

Not sure I follow the question. Perhaps prepare a screencast and show what you’re experiencing?

Its always showing me this message when I select an element and save a file.

I don’t see a select face node in your graph though… was there one before?

yes the one that I sent was a demo only . I’m working on getting that error again to post it. But in my case what might be the issue?

Can’t say unless we see how you triggered the error. Some possibilities:

A conflicting add-in;
Bad install;
Corrupted node source code;
A system setting blocking execution;
Gremlins;
System resources lacking to sufficiently pull that code;
AV/ASW issue;
Missing dependency in your OS;
Bad Revit install;

ok I will check more If I can get the error again.
