We're seeing a large number of schema validation errors related to accounts_cirrus.enrollment_status_v1 which started showing up on 2026-01-08. The nimbus_user_id is expected to be a string, but the in the pings it's being sent it is set to null.

I reached out to the nimbus team here: https://mozilla.slack.com/archives/CANCHH6R1/p1768242443277429
