ERROR: Nearly zero bi-normals (Tolerance of 1E-4)

Hello, guys! Thanks for trying to help me

Everytime I import this mesh into UE4, I have this message (Nearly zero bi-normals...)

I exported it from blender 2.8. FBX file. UVs are good.

I don't know what's problem, could you help me please?

This is definitely something to do with the uvs though. Could you show the uvmap? Even if you think its ok.
