Unable to persist create records using Loki as adapter

I have added watermelondb + Loki to a project and when creating records the raw values are all the default values of empty strings and 0 numbers. When I log out the records during the batch creation they are there but upon retrieval the raw values are the defaults.

When writing directly to the raw field it does persist, ie: lpEvent._raw.block_number

Here is the actual create action in the repo branch: https://github.com/status-im/liquid-funding/blob/watermelon-data-persist/app/actions/lpEvents.js#L19

It seems using a decorator on a class property is simply ignored by babel for some reason.

I got it to work using this approach:

function initialize(target, name, descriptor) {
  descriptor.initializer = true
}

export default class LpEvent extends Model {

  static table = 'lp_events'
  
  @field('address')
  @initialize
  address() {}
}

By declaring it as a method babel no longer discards it, and I had to create the initialize decorator in order to get around this invariant: https://github.com/Nozbe/WatermelonDB/blob/master/src/decorators/common.js#L21-L25

Which leads me to ask, why is that invariant needed?

I believe I found the issue. I think it’s related to: https://github.com/babel/babel/issues/8417

Here is the fix in my webpack config: https://github.com/status-im/liquid-funding/commit/2bc3e5fd3426bd91ee8d70e2d43b9ce11e370299
