API Call to Municipalities Returns "Unknown TIGER Release"

After flushing the redis cache the API is failing to return results when it makes a GET request to municipalities:

My guess/understanding is that this should return the geojson of the map that would appear on the front page. I need to figure out where it is coming from and why it is returning this. I would expect that the cache would simply repopulate.
