Get "That's not a Minecraft skin, silly" when trying to use custom skins on the mobile version

I tried to use a custom skin in the Minecraft pocket edition And every it tells me "That's not a Minecraft skin, silly" And I don't know what to do, this problem didn't exist before 1.20.0.22, So I waited until it was resolved, but we are in 1.20.10.20 And the problem still exists, all the skins I have are from NameMC with is a specialized site for skins, I will report this issue until it is resolved, sorry for my english I used google translate
