Short description of error

While trying to export an FBX file I got the following traceback error;

Traceback (most recent call last):

location: <unknown location>:-1

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

I've attached the blend file. Open the file and attempt to export as FBX.

FBX export selections;

Main-
Selected objects (redundant in this file I sent you, but I'm always exporting from a file with multiple objects.)

Geometry-
Dropdown menu to Face
Select Tangent Space

Armature-
Deselect Add Leaf Bones

Every time I do this, I get the Traceback error. I copied the object into blender 2.79b and it works fine with the same export settings. I've made a couple dozen wheels this way in 2.79b, this is my first try at 2.8

I apologize in advance for not really know how this system works.

I see that the export bug error was listed as resolved, and thusly closed. I downloaded the latest daily build today, Dec 10th and I'm still experiencing the same error. Are the fixes not applied in the daily builds? Do I just need to follow #58881 to find out when the fix is implemented? Do I need to wait until the next version, something like 2.80.1 or whatever it would be?

Fixes should end up in daily builds automatically. Are you sure you are running the latest build? What's the date on the splash screen?

Checking the latest Windows 64 bit build, here it has different code than the one shown in your error message.

OK, that was my fault. Even though I downloaded the build from Dec 10th, and even overwrote the files in my blender folder with the new ones, the splash screen was showing up as the Dec 6th version, so I'm not sure why, but my shortcut let me astray. Now I just have to figure out where I went wrong with the shortcut.
