.SVG “This design cannot be printed on the selected product. Please change product or design.”

Hello, I have a big problem to upload my logo. The idea is to put it in embroidery on a t-shirt, unfortunately this message appears every time I upload my . svg
In addition, the logo appears in black while it is basic orange and white…
I followed the help page for “Optimize a vector graphic” but the problem persists.
