mmdbridge_vmd Error: <class 'Index Error'>: invalid string position: File "<string>", line 31, in <module>

I tried to mmdbridge_vmd to bake physics & ik (expert_mode = 0). However, all the bones were skipped. This seems to be #7 issue, because my system locale was not Japanese. So, I changed system locale to Japanese tried again. This time "<class 'Index Error'>: invalid string position: File "", line 31, in " appeared.
