Bug report - Maya 2020.2 is throwing me an error on export

[anna22]

Hi guys,
Just had to upgrade to Maya 2020.2 and the plug in is throwing me an error on export. I select my geometry and run the exporter but nothing is being exported. My file is 1KB
The model is just a regular test default sphere with a default aiStandard shader.
See screenshot with error log below. Thank you!

Looks like this is the same issue i reported here:

"Optimize Vertices" Option Breaks Latest Version of Maya Exporter (20200917.1)

With the latest version of the Maya Exporter in Maya 2019, if I have “Optimize Vertices” checked, every piece of geometry emits the error below during export, and in the GLTF it just ends up as a dummy node with no geometry. This wasn’t the case in the previous version of the exporter I was using (20200721.1). Without “Optimize Vertices” the export ends up being more than 5x as large in terms of file size. To repro, just create a simple primitive in Maya 2019 and use the babylon exporter to cre…

@pnut yes it is! Unchecking “optimize vertices” got the model out for me. Thanks so much man for the tip!!! Saved my day! Funny enough though my file ended up being roughly the same size as the one from Maya 2018 exporter. Just 18 kb higher. So not a huge change for me on that side, but yes- checking on “optimize vertices” option does creates a dummy node with no geometry.
