CRNA app throws a lot of console errors on iPhone device

Description

Today, my working CRNA app started to throw lots of console errors if run on iPhone device. This doesn’t happens on Android device.

The very same app was working just fine yesterday on iPhone device!

Expected Behavior

CRNA app work just fine with iPhone device like yesterday

Observed Behavior

The app keeps diplaying loading icon and indicates “Downloading JavaScript bundle”, also throws insanely lots of errors logs in console +2100 in 10 seconds!

[UPDATE]: If I run the project from XDE client app, it works…

Excerpt:

`ScrollView` has no propType for native prop `RCTScrollView.contentInsetAdjustmentBehavior` of native type `UIScrollViewContentInsetAdjustmentBehavior`
If you haven't changed this prop yourself, this usually means that your versions of the native code and JavaScript code are out of sync. Updating both should make this error go away.

For me, the issue was some incompatibility with the versions of some modules, and the error was the same.

What I did to solve the problem was:

1. Create a new project using create-react-native-app foo
2. Open your project’s package.json and update the versions of the dependencies to match those in foo’s package.json.
3. Check that expo version match the sdkVersion in the file app.json and update if necessary.
4. Delete node_modules and reinstall all the packages.

This fixed it for me. I hope it helps!

Hi everyone! It doesn’t look like there’s an obvious reproduction of this issue at the moment. If you’re consistently seeing these errors please post back with an example of a project I can clone that will trigger these error logs and I’ll reopen. Thanks!
