Incorrect

The function was called incorrectly:

datasets = APS_utils.json_import("bluesky_data.zip")

Correct

Since the ZIP file was written with:

APS_utils.json_export(headers, "data.json", zipfilename="bluesky_data.zip")

the contents should be imported with:

datasets = APS_utils.json_export("data.json", zipfilename="bluesky_data.zip")
