JSONDecodeError when running oapi.get_structures_with_sets([1])

[pderdeyn]

Describe the bug
I want to load a structure graph using the OntologiesApi from AllenSDK. I've used this code in the past perfectly fine and have not updated this conda environment since the last time I ran it. Today, I am getting JSONDecodeError. Perhaps this is an API issue?

To Reproduce

from allensdk.api.queries.ontologies_api import OntologiesApi
oapi = OntologiesApi()
structure_graph = oapi.get_structures_with_sets([1])

Expected behavior
structure_graph should successfully load in the proper set of structures

Actual Behavior

JSONDecodeError                           Traceback (most recent call last)

Today it is working. I restarted my jupyter notebook and the exact same code was able to run. Not sure what was causing the issue. I'll leave the bug open for y'all to categorize and record according to your process, if you'd like to
