Maya blendshapes to UE 4.12

Hello all. So, I’m experimenting with blendshapes in Maya 2017 and I created a sphere as in the video below:

I exported the object as FBX Maya 2013 version, having blendshapes checked. However, when I try to import the exported FBX into UE4, it loads up to 75% and then pops a window saying "Failed to import 'C:\Users\dean_\Desktop\Maya Projects\Exported\new.fbx'. Failed to create asset '/Game/new'".

Am I doing something wrong? Is there a compatibility issue that I’m not aware of?
Any suggestions on how I should create and import FBX models with morph targets?
Thanks in advance!
