e.observable.object is undefined when using 0.57.0 on expo #237

Closed jeloagnasin closed 3 years ago

jeloagnasin commented 3 years ago

I created a repo with the simplest way to reproduce the error: https://github.com/jeloagnasin/mobx-keystone-issue.

When I was using mobx-keystone@0.57.0 on expo, I receive the following error:

TypeError: undefined is not an object (evaluating 'e.observable.object')

This error is located at:
    in App (created by ExpoRoot)

If I downgrade to mobx-keystone@0.54.0, it works fine.

expo install mobx-keystone@~0.54.0

It seems to work for me with node 16 and the web version in the latest chrome (at least I can see the ·Open up App.tsx to start working on your app!" in chrome without any errors in the console). Where are you getting the error? An android device, ios...?

Found that it actually happened on android. Please try 0.57.1

I'll assume it was fixed. Please reopen if needed.
