Cannot load subscription list for "ddmadmin" user

[TimoWilken]

Description

I get an error on the subscription list/search page, e.g. here. This worked yesterday (2026-06-29), but today (2026-06-30) the page just refreshes itself a few times, then the following popup opens:

The error seems to come from an API call to https://atlas-rucio-webui.cern.ch/api/feature/list-subscription-rule-states?account=ddmadmin, which returns the following JSON:

{"status":"error","name":"","state_ok":0,"state_replicating":0,"state_stuck":0,"state_suspended":0,"state_waiting_approval":0,"state_inject":0,"message":"Gateway Error: TypeError: Cannot read properties of null (reading 'toUpperCase')}"}

Steps to reproduce

1. Open https://atlas-rucio-webui.cern.ch/subscriptions?account=ddmadmin&autoSearch=true.
2. Wait while the page reloads itself some (variable) number of times.
3. Observe a red popup with the error message "Gateway Error: TypeError: Cannot read properties of null (reading 'toUpperCase')}".
