upload character problems

[Rubén29743335pq4r]

Hi. I'm trying to upload a character to Mixamo from Blender. The character has several parts separately, head, hands, jacket, pants, and boots. When I upload the character to Mixamo, it gives me an error and doesn't let me upload the model. I haven't used metallic or roughness maps. How should characters be modeled so that they can be uploaded without any problem? Thank you.

we can't read your mind mate... please share the model and I'll test it

This is the character in .obj format that is not working for me: https://we.tl/t-Ivqb9T6aDg
