I ran into an issue when importing SVGs made in Adobe Illustrator – paths would randomly throw up an open path error, but inconsistently. In illustrator, they were showing up as closed paths (AI will tell you if it’s open or closed in the info tab) but Easel didn’t like them.
I was finally able to figure it out – Easel doesn’t like paths where the stroke is set to align to outside or inside. You should set it to “align to center” before exporting.
I didn’t see a solution posted here, so I thought I’d post one in case anyone else is encountering the same problem.
