Dyn file doesn't open on old version(2019) of Revit after modified on recent version(2022)

Some of my dyn files doesn’t open on old version after I modified it on recent version even though I used only old traditional nodes without any nodes from packages.
When I try to open these files, Dynamo just open new empty graph without any error messages.
Any idea?

Can you check if you’re using the up-to-date version 2.0.4 for Revit 2019?

Can you share the error screen while opening the dyn file?

There is no error message like i said. just open empty new file without any message.

Check the dynamo error log once it is opened, to see this log follow what i describe in the following post

Hi there Dynamo users. Same issues here. Some of my dyn files (with no nodes from packages on it) don’t open in older dynamo versions when they where created in Revit 2022 and Dynamo 2.10.
I have to say though that they had python nodes.
@Hyunu_Kim did you find any solution?

@Brendan_Cassidy the problem i think is that the node doesn’t open at all. Is like a ghost file, il opens a new blank work space…

It may open as a Blank file but within the error log it may say “File not opened because of …”. Therefore helping to root out the cause.

Not yet.

Hello Brendan. Where can I find this error log?

Hold down shift and press the up arrow. Where the log is saved will be listed in the console that displays once you do this.

@Hyunu_Kim and @Pit can you both post your DYN files and logs here so the community can test opening on other systems to see what the blocker is?

I can’t see any log.

This is a sample file…
version test.dyn (16.8 KB)

@JacobSmall Anything found?
