Short description of error
I want to import into Blender a FBX file but a sign appears, it says "TypeError: object of type
NoneTypehas no len ()".I downloaded the file from mixamo
Exact steps for others to reproduce the error
I open import I choose the FBX file and it appears the sign with an error.
I've already solved the problem.

Im getting the same error. Not sure what I have done differently from times before when I import a FBX file from Mixamo. How did you solve this issue?
Added subscriber: @Raelx
I get the same error with the attached file grommet5.fbx.
This data originate in PTC Creo, is exported from there as a STEP, STEP is imported into Keyshot, exported from Keyshot as FBX. The FBX opens in Window 3D Viewer. If this one part is in any thing (like large assembly) exported from Creo and flowed thru the same process I get this error upon import to Blender.

Can confirm this file wont import.
Looks like the custom normals (
LayerElementNormal) have no data though [at least this is what is suggested here -- this might actually be more of a problem of the preceeding pipeline than blender's]However, I think we can be act more graceful here, just print a warning and continue @mont29?
Will confirm for now, Diff incoming...
Note: workaround is to just deselect the
Include>Custom NormalsoptionMy problem was that when I imported and the new window was opened, I didn't click on "selected objects" (it´s on the right side under the tab "include").
After that, I could do all the steps and imported my FBX from Mixamo without any problem.
