Calculator::Process() Error during text embedding on MacOS

[ZeroCho]

Have I written custom code (as opposed to using a stock example script provided in MediaPipe)

Yes

OS Platform and Distribution

MacOS 15.1.1(M3 Apple Silicon)

MediaPipe Tasks SDK version

0.10.20

Task name (e.g. Image classification, Gesture recognition etc.)

text_embedder.embed

Programming Language and version (e.g. C++, Python, Java)

Python3.11.6

Describe the actual behavior

error happened

Describe the expected behaviour

embedding output come out

Standalone code/steps you may have used to try to get what you need

1. copy my code attached 2. run python3 text-embedder.py puppy
