Unknown Error while generating motion & Place al markers on the character errors

[흑흑]

hello,  I rigged the model like this and used the no fingers skeleton, but those 2 errors appear.

I removed the character's clothes or hair and tried it, but the same result came out

can someone help me?

repace the head after rigging is the only workflow to fix big heads that i'm aware of
