A ParseTextProto error occurs in the 'LandmarksToTensorCalculator' of the media pipe blendshapes on Unreal Engine 5.

[JhinSH]

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

Yes

OS Platform and Distribution

Windows

MediaPipe Tasks SDK version

2.9.5

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

Blendshapes value to UE5

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

C++, pbtxt

Describe the actual behavior

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

I'm trying to extract the Unreal Engine Blendshape value using wonfei(https://github.com/wongfei/ue4-mediapipe-plugin)'s media pipe. Currently, I'm experiencing the following error and haven't made progress for a few days. Please help.

that's my error message.

Hi @JhinSH,

We have not tested this scenario and do not have official support for Unreal Engine. It would be best to raise the issue in the same repository and follow up there for further assistance. Unfortunately, we will not be able to assist further. Hope you can understand.

Thank you!!
