ValueError: Failed to convert a NumPy array to a Tensor (Unsupported object type NoneType).

I am trying to convert an onnx model to keras but the value error pops up. I am using the following versions:

python 3.5 tensorflow 2.2 onnx 1.3 onnx2keras 0.0.20

Fixes for this will be highly appreciated!
