Can you tell me the steps to create an error condition?
I imported the following model, set up Animator and tested it, but I could not find any errors.

@hiroj
CesiumMan is use animations.
test.zip
This model is download from unity assets store.
When exporting glb, there will be many warnings and no errors. But this glb can not be loaded.

Environment: unity 2017.5.5f1

Any chance of trying later versions like unity 2018, 2019? Not sure it will work though

I had the same issue. Deleting the Animator fixed it for me.

Settings of reproduction with CesiumMan. Unity 2013.3.12f1.

Nice! This interface looks like you were using Unity 2019?
@643364103 Please try akehir's method with the latest Unity version and see if it works for you.
Thanks,
