While freezing model : IndexError: list index out of range

I've successfully saved checkpoints in directory `./ckpts/checkpoint/ `and when I'm trying to freeze the model it is creating an empty **layer.js** file but unable to create **.pb** file.

The error I' getting upon executing the instruction: `python main.py --dataset faces --input_height=64` is attached below, seems like some code error in `to_json` function.

What should I do?
```
...
