Description

A clear description of the bug
I cannot save my workflow through the napari-allencell-segmenter in the napari GUI. I am new to napari and do not know Python, so this may be a very basic issue that can be fixed easily. The error doesn't change if I try to save before or after setting the pre-processing, core, and post-processing steps. My workflow is for h2b_interphase.

Expected Behavior

What did you expect to happen instead?
I expected it to save and tell me where it saved. Instead it does not save a .json file and gives an error message.

Reproduction

Please list the exact steps we can take to reproduce this bug.

1. Upload images. Mine had to have a very narrow contrast range to see the nuclei
2. Create new workflow
3. Run intensity rescale
4. Press save workflow. This is where the error popped up.
