Error Realm initialization with sync enabled due to mismatch schema is not calling onError function

How frequently does the bug occur?

Always

Description

Check the following line:

https://github.com/realm/realm-js/blob/91de9446242a3dc7aaaf640925af360b5d91a7d2/packages/realm-react/src/RealmProvider.tsx#L140

It is calling the console.error directly. This way we cannot handle this error on user device.

We have configured the application to only open the realm for the first time after DownloadBeforeOpen.

Stacktrace & log output

[Error: The following changes cannot be made in additive-only schema mode:
- Property 'ObjectType.idInitialStatusIntegration' has been made required.
- Property 'ObjectType.idInitialStatusPDA' has been made required.

- Property 'ObjectType.nmCdField' has been made required.

If your app is running in development mode, you can delete the realm and restart the app to update your schema.]

@gfrancischini Thank you for reporting.

I believe that we should extend @realm/react with an option not to shallow the exceptions from Realm.open(). We can either rethrow the exception or call the onError callback (if defined).
