Use Meshio to read the grid data(.nas) generated by Comsol, KeyError: 'wedge15'

The code is as follows:

> import meshio
> nas = meshio.read("mesh/file_name.nas")

An error is reported after the running：

Traceback (most recent call last):
  File "/opt/project/learn_fenics/meshtrans.py", line 2, in <module>

What does this error mean? Can’t meshio read a wedge mesh with 15 nodes?
How to use meshio to read .nas mesh? Btw, the mesh(.stl) exported from the same comsol model can be read smoothly.
Looking forward to the answer.Big thanks！
