hip_to_root raised "none type" object has no attribute 'action' when processing error

[AutomaticFX]

Hello - happy new year all.
new to using this blender/mixamo add-on feature. am using a character from BigMediumSmall Post Apocalypse bundle. the character, named D2, was already set up as FBX in a folder for import into Mixamo, and it uploaded to mixamo no problem. we downloaded a number of animations without issue. they all work fine in UE5. we wanted to add root bone so followed process per instructions, however, getting the above mentioned error:
hip_to_root raised "none type" object has no attribute 'action' when processing error D2_Mixamo.fbx
would appreciate any further insight/ suggestions into fixing this issue.
Thank you!

Please supply direct links, to the animations that produce problems. I can not even find the Packs you mentioned. So i can not reproduce the Issue.

https://www.mixamo.com/#/?page=1&query=zombie+walk&type=Motion%2CMotionPack If I remember correctly, this was the anim I was using. I think it occurs for any root motion anim.

I was using a skeleton generated using the mixamo autorigger on these models https://maxparata.itch.io/voxel-zombies

Ran into this issue when batch converting. Problem occurs when the rigged character (without any animation) is included in the input folder. Removing it fixed the issue for me!
