Following up on the deprecation above.. on current core (v2026.8.0-latest.1) it’s not just a warning any more, the report page itself looks broken.
/admin/plugins/fingerprint comes up with an empty “latest matches” and flagged list, and the console throws:
Uncaught (in promise) TypeError: Cannot convert undefined or null to object
at Object.values (<anonymous>)
