Error on creation of a schema via POST

Environment: Running latest/edge of the juju deployment of the identity platform with the admin-ui build from current master.

We created a new schema via API


curl -d '{

      "$id":"https://schemas.canonical.com/presets/kratos/test_v0.json",

   }
}' -X POST -H 'Content-Type: application/json' http://127.0.0.1:8000/api/v0/schemas

Got an empty response from the API. The logs of admin-ui revealed this trace:
