Files become corrupt for no known reason

[ChrisBStudio]

Hi All,

I am having issues with files becoming corrupted for no reason in Dynamo. This has happened on 2 separate occasions where I have closed the file for the day and the next day it will not open.

I am using Dynamo Revit 2.13.1.5510 and the script was created in this version as well. I have had an issue before with old packages, but I cleared all the packages and downloaded only the latest versions to get a fresh start.

I use Dynamo a lot in our office and up until now it has been very reliable. Unfortunately if this becomes a common problem people will loose their trust in its reliability. If some could help with some information on why this might be happening, it would be greatly appreciated.

Thankyou

Chris

hi @ChrisBStudio When you mention unknown error, what do you see when you try to open the dyn?

Can you also provide one of the damaged scripts?

[ChrisBStudio]

This is the error message

And this is the script. Just change the extension to .dyn

Hi @ChrisBStudio the issue is that the file contains "NodeLibraryDependencies": null, I don't know how this property became null but we can make deserialization more robust, in any case to fix this file - just replace it with the following in a text editor:

"NodeLibraryDependencies": [],

should be fixed after this: https://github.com/DynamoDS/Dynamo/pull/13423
