I'm facing the same issue

[Andrew M]

Also here after upgrading my react-native project to 0.62

[Shivansh Rajpoot]

I temporarily resolved it by using react-dom as dev dependency, but obviously it's not the right way.

npm i --save-dev react-dom

[Andrew M]

I downgraded to

"mobx-react": "=6.1.7",

and its OK now

[Rander Gabriel de Oliveira Rodrigues]

I'm facing it using react-native version 0.61.1. I realized that is stopped working on the last week. We didn't change any dependency related to mobx-react but our CI builds stopped working. We are using

"mobx-react": "^6.1.1",

When we clean the build cache (deleting /node_modules) in a development machine the problem appears.

I apologize for the issues, small oversight from yesterday's release. Please upgrade to 6.2.1 and mind following instructions in https://github.com/mobxjs/mobx-react#observer-batching

[Andrew M]

@FredyC Upgrading to 6.2.1 and adding observer batching seems to have fixed the react-dom issue, but may have introduced another.

Since upgrading I now sometimes have crashes with

TypeError: Object.defineProperty() called on non-object
   at defineProperty (native)
    at setHiddenProp (mobx-react)

Removing the import for observer batching stops this from happening. I can't reproduce it reliably. This is on react-native 0.62.1, mobx-react 6.2.1, mobx 5.15.4, mobx-state-tree 3.15.0

[Daniel K.]

@AndrewMorsillo Please open a new issue and try to reproduce with React as I cannot imagine how React Native could be problematic in that sense.
