I trained a mobilenet_v3_small model using Tensorflow version 1.15.2 (object detection API), then converted it to tfjs. I was able to make predictions in python but when I try to run the model using tfjs, I get the above error. I am not sure that it's related directly but in the .json file the number 2034 appears in: ...{"name": "Postprocessor/ExpandDims", "shape": [1, 2034, 3], "dtype": "float32"}.
