Error on faas pyramid (after zarr groups normalization)

[Yu-AnChen]

Ran into an error when trying to run the save_exhibit_pyramid.py script on a faas pyramid generated by ashlar at the latest commit (c32f018). Checked out a previous commit (aaefbdd), and the same command ran through. It seems to me this commit (cf32a1e) introduced the issue
