[ios][eas][expo-branch][managed-workflow] Branch params is always empty when using eas build

Summary

I have migrated my app to 41 SDK, and the new eas build pipeline. When the app is built with the new eas build pipeline (managed workflow), branch does not call the callback with params. So, the deep linking feature is broken.

With eas build

{"error":null,"params":{"+is_first_session":true,"+clicked_branch_link":false,"+rn_cached_initial_event":true},"uri":null}

With expo build

{"error":null,"params":{"~marketing":true,"+is_first_session":false,"debug":"true","$marketing_title":"Debug","~creation_source":1,"~id":920259617150271500,"+clicked_branch_link":true}

This is same code running with SDK 41.

Let me know if you need more info guys

Managed or bare workflow? If you have ios/ or android/ directories in your project, the answer is bare!

managed

What platform(s) does this occur on?

iOS

SDK Version (managed workflow only)

Reproducible demo or steps to reproduce from a blank project

import Branch from "expo-branch";
import Constants from "expo-constants";
import * as React from "react";
import { StyleSheet, Text, View } from "react-native";

export default function App() {
    const [params, setParams] = React.useState(null);

    React.useEffect(() => {
        Branch.subscribe(bundle => {
            setParams(bundle);
        });
    }, []);

    return (
        <View style={styles.container}>
            <Text style={styles.paragraph}>{params}</Text>
        </View>
    );
}

const styles = StyleSheet.create({
    container: {
        flex: 1,
        justifyContent: "center",
        paddingTop: Constants.statusBarHeight,
        backgroundColor: "#ecf0f1",
        padding: 8,
    },
    paragraph: {

        fontSize: 18,
        fontWeight: "bold",
        textAlign: "center",
    },
});

expo-branch isn’t compatible with EAS Build. the long term solution here is likely that we will be deprecating expo-branch and recommending that users who want to use branch should use the official react-native-branch library with a config plugin. if someone wants to have a shot at writing a config plugin for this, please do!

Hey @brentvatne, Do you have any information about this issue? I have to switch back to expo build because this.
