Hey Happy New Year to you too.
If memory serves you will need to render your Blender scene. I would suggest an image sequence with transparency.
Then import this sequence into After Effects. Parent this to your element with the tracked data keyframes.
The objects in your Blender scene do not get exported in the JSX only the tracking data.
Hope this helps.

Hi there Adrian,

I recently created a repo here fixing for 2.9: https://github.com/kenxjay/io-export-after-effects-2.9
