Observed here among other places: https://ci.realm.io/blue/organizations/jenkins/realm%2Frealm-kotlin/detail/PR-1559/5/tests and https://ci.realm.io/blue/organizations/jenkins/realm%2Frealm-kotlin/detail/main/183/tests/

#1559 updates the CI BaaS to 2023-11-02 which have not yet shown the issue, so might just be incompatible versions. Locally built BaaS does not show it.
