When I try to select the Custom Outline option of the Sprite Editor in the Bundle Version, it generates a bunch of errors and doesn't load the editor:

These errors seem to appear every frame till I close the window

I know that the Bundle Version is still in preview and isn't ready, but I just wanted to point out this bug and hope you'll fix it. I love this importer, but I think that having subfolders for each Aseprite file is kind of bulky.
Thanks.
I'm using the 1.0.4 version in Unity 2019.4.19f1
