UPDATE: It wasn’t the file name. I tried changing it and recreating it in Easel several times. The issue turned out to be something with the way Easel was creating the file using a bit to drill a hole that was too small for the size drawn. Once I changed the size bit in Easel it worked fin.
As far as I remember, I think I got this kind of error when the file name was strange. Try to rename it to smth simple, like “aaaa”
I may be wrong though…
