are you changing any settings? I followed your example an had no error, exported with vert color and imported back with vert color.

I've got a number of default settings changed in Preferences, but that shouldn't matter for an X3D export.

I can consistently reproduce the error here. I've sent along a screenshot.

Looking at the error I suspect it's got something to do with no assigned material, while there are vertex colors?

Please attach here a .x3d file that fails to import…

I'm sorry, I haven't got X3D files I can publicly share. But I can reproduce the error every time if I follow the steps to reproduce the error. See the above reply for the error I get.

If you cannot share a 'work' x3d file, then you should be able to create a dummy one demonstrating the issue…

The problem is: I can't import or export an X3D file. When I export a scene, I get the error and the file is 0 bytes.

Simple meshes exports fine (Using 2.81a). However when I add SubD modifier it gives below error (I also get same error with vertex colors):

Please report export issue in a separate thread, only ONE issue per task, otherwise it is impossible to manage things.

That suzanne.x3d file imports without any error here…

I've attached a scene I can't export as an X3D (default export settings of the add-on).

This previous report might be related to the issue?X3D export error.blend
