(Juniper) Cannot add access status types

Reported by a customer live with Iris,

1. When I went to Settings > eHoldings > Access Status Types
2. and tried to add an access status type, nothing happens when I click save.
3. There is nothing in the network response tab of dev tools, but the attached error appears in the console.
4. I was able to replicate this on Bugfest Iris and Snapshot as well, though the snapshot error is slightly different

Question: Does MODKBEKBJ-584 resolve this issue?
