How to fix "INTERNAL ERROR: list index out of range" when uploading an onnx model to STM32Cube.AI

[APerd.1]

Hello!

I'm getting the error: INTERNAL ERROR: list index out of range when uploading an onnx model to STM32Cube.AI and run analysis. I have validated my model with other tools like netron.app and it is correct. I would appreciate if anyone could help to figure out what could be the problem? I attach my model below in case someone can help me. Thanks in advance. Regards!

I forgot to mention that this model was generated in Matlab with exportONNXNetwork function, in case it may be of help.

The error is in the import of the LSTM layer, probably due to the way Matlab exports the LSTM layer.

I forwarded the network to the development team.
