Help users resolve 'Udon C# Program Asset is null' error

[Faxmashine]

Feature Description: Users often create empty Udon C# Program Assets. This prevents UdonSharp from compiling. Users often do not understand the error. Possible reasons:

• They're inexperienced with UdonSharp
• They received their UdonSharp assets from someone else
• They created the Asset on accident and forgot about it
• Double-clicking the error does not highlight the asset (Unconfirmed)

Regardless, we should help users identify the issue, and suggest a solution.

For example:

• The error should indicate that the file should either be deleted, or a source C# script should be added
• The error could be downgraded to a warning, as was the case before U# 1.0

Is there any update to this? I made the mistake of migrating my Unity project to VCC, and all of the sudden my UdonSharp is broken and so are my worlds which I can no longer fix or update.

I noticed my UdonGraphs were fine, but any instance of an UdonSharp script were screwed. So I deleted them all. I now have zero items with UdonSharp scripts on them, and yet, no matter which Scene I open in the entire project, I'm told there's a "Cube(2)" with a null script. There isn't a single "Cube(2)" in any scene in the entire Project. It makes no sense. Two weeks of failed attempts to fix now.

You may have a prefab named that which you need to update. You can try re-migrating the old version of your project that VCC leaves. This issue doesn't seem relevant to your problem though and sounds more like Unity just broke during migration.

I am actually in this very position, I am completly new to creating a world, and I grabbed a bunch of prefabs to throw into my world and for the most part they work, except for a prefab bowling lane setup that is showing that error, and it's referring to a "joiner" in the prefab, but I cannot for the life of me figure out what is wrong and I attempted to try contact the prefab creator by email as that was the only way to contact them but have yet to get a responce.
