Does anybody know what AttributeError: 'Node' object has no attribute 'data_type'. Did you mean: 'rna_type'? means? Getting this message while I’m exporting animated model.
Welcome

Hmm… 
well… this seems to be more a hint for developers than for users… Does it export ? Then you may not bother ?
You may have to elaborate this to get a more suited answer.
Well Yeah, it’s python error
Traceback (most recent call last)
So are you telling it works ?
No
It doesn’t work 
It show python error when I try to export gltf and that’s it. Thank you for congrats by the way!
PEACE!
The error message should tell you more that just ‘AttributeError’… Can you share the whole console output?
