On my local deployment test, updating to v2 the following error shows up:

Comes from old schema:

OpenHaus [direct: primary] OpenHaus> db.store.find()
[
  {
    _id: ObjectId("6283effb323aeb5f1a1e3a3b"),
    key: 'interval',
    description: 'API Polling interval',
    namespace: 'd11e7f38-91cb-4f32-89e8-3452f624bb47',
    value: 3000,
    timestamps: { created: 1652813819453, updated: null }
  }
]

How migrate that?!
