Mesh cannot import into S4S

Hi all, I have made a piece of mesh and I do all the steps like transferring uv_1 and weights, vertex paint, making the cut numbers into 0000.

Then I pick a male swimwear which has only 1 cut. (Yes, this is a dress for male.)

However, once I import the mesh into S4S, it loads a bit, but after all, the mesh isn't imported.

Here is the S4S log error:

I have really no idea what goes wrong, as I made quite a number of mesh and haven't face this problem before.

Here are my .blend and .package files.

Thanks a lot!
