BlendShape Export failed: Invalid solver node

Here is my code:

import py_audio2face as pya2f
a2f = pya2f.Audio2Face()

Generate animation for a single audio file

a2f.audio2face_single(
audio_file_path="E:/Python/py_audio2face_test/audio/test.wav", # path of the audio file you want to animate
output_path="E:/Python/py_audio2face_test/output/animation.usd", # path where the animation file will be saved
fps=60, # frames per second for the animation. Higher fps will result in smoother animations and longer processing time
emotion_auto_detect=True # automatically detect emotions in the audio file. If false the set emotion will be used
)
