React Native todo app get stuck on npm and crashes when built on Mac

I'm trying to follow the tutorial here, but every time I run the sample app it crashes immediately.
https://www.mongodb.com/docs/atlas/app-services/tutorial/react-native/

Here's what I'm running:

realm-cli pull --remote [name of my app in atlas] --template react-native.todo.flex
cd TutorialApp/frontend/react-native.todo.flex
npm install

This will get stuck on reifying realm. So I blow away node_modules and packages-lock.json and run yarn instead.

rm -rf node_modules package-lock.json
yarn
npx pod-install
npx react-native run-ios

It takes a long time, but eventually tries to run the app. When it does, the app simply crashes with a BAD_ACCESS error. This is really weird because I'm able to build and run other React Native apps.

What gives? Am I doing something wrong here?

Flutter - atlasUrl is missing in config

Atlas url is used in project but is missing in config

class Config extends ChangeNotifier {
  late String appId;
  late String? atlasUrl;
  late Uri baseUrl;

  Config._create(dynamic realmConfig) {
    appId = realmConfig['appId'];
    atlasUrl = realmConfig['dataExplorerLink'];
    baseUrl = Uri.parse(realmConfig['baseUrl']);
  }

  static Future<Config> getConfig(String jsonConfigPath) async {
    dynamic realmConfig =
        json.decode(await rootBundle.loadString(jsonConfigPath));

    var config = Config._create(realmConfig);

    return config;
  }
}

Call To Function is not passing the arguments

Hello team. Not sure if this is the right channel. But I was working on a presentation and using the template tiered from our docs, I realise there was something wrong.

So, inspecting further, I've seen that the call to function joinTeam is doing

const adminFuncArgs = [admin.id, "greenTeam", true /* make admin */];
const adminFuncResult = await admin.callFunction("joinTeam", adminFuncArgs);

The arguments are passed in an Array. The App Services function is defined as exports = async function (userId, teamName, isAdmin = false) and the problem is that all the arguments are stored in userId instead of being spread.

Therefore userId = [admin.id, "greenTeam", true] and teamName = undefined. So the $set is not working as expected as the filter will never work

The fix is pretty simple, just by editing two lines as follows:

const adminFuncResult = await admin.callFunction("joinTeam", admin.id, "greenTeam", true);
const funcResult = await member.callFunction("joinTeam", member.id, "greenTeam", false);

Realm Prop load error

When running the code through the android simulator, it errors out when initializing the RealmProvider. I get the following errors:

Crash on Mac Catalyst (SwiftUI)

Howdy.

It would be lovely since I used the logics in this SwiftUI ToDo example in my project you help me to figure out how can I fix my issue on realm/realm-swift#8079

Regards,

The react-native template pulled from realm platform does not initiate correctly with xcode 69.5

The app is correctly built, but when it is initiated, appears the next error on the simulator:

I execute the npx react-native init command from the app main folder, the one which contains app.json, realm.json, ios and android folders, etc...

What am I supposed to do different?

Thank a lot in advance!

Android With Kotlin Tutorial

I have followed the Android With Kotlin Tutorial but when I download the zip containing the front end code it is empty. As a result I used the CLI (appservices pull) but I cannot get the app to function correctly and I am not sure if this is an issue with the template or configuration that I have missed while following the tutorial.

On the Android device I can login successfully and get the following in the logcat
LoginEvent com.mongodb.app I User logged in successfully.

but then I am presented with a black screen and the logcat repeatedly outputs

REALM com.mongodb.app W [Core] Reading failed: End of input

What am I missing?

EMpty template app

When I download the template app it's empty - and I want to download because of the link

.net maui template app

Do you recommend using the Toolkit QueryProperty

https://github.com/mongodb-developer/HouseMovingAssistant/blob/main/ViewModels/EditMovingTaskPageViewModel.cs

or ApplyQueryAttributes

SwiftUI template app unable to maintain connection with flexible sync

The SwiftUI template todo app is unable to maintain a connection with MongoDB. The app itself works just fine, but it is unable to sync. The steps I'm taking are:

1. Create a new app and download zip file from Atlas App Services
2. Ensure appId and appUrl are correct in atlasConfig.plist
3. Build and launch app on iPhone 14 Pro simulator
4. Create a user via app and log in to the app
5. Create todo items

I can see the created user in App Services, but no todos are ever synced. Opening the app on a different simulator confirms that there is no syncing happening. The following is output when the app launches and attempts to connect to flexible sync (I've removed some identifying info from these logs):

Sync: Realm sync client ([realm-core-13.10.1])
Sync: Connection[1]: Session[1]: Binding '[obfuscatedpath]/flx_sync_default.realm' to ''
Sync: Connection[1]: Session[1]: client_reset_config = false, Realm exists = true, client reset = false
Sync: Connected to endpoint 'x.xx.xxx.xx:xxx' (from 'xxx.xxx.x.xx:xxxxx')
Sync: Connection[1]: Closing the websocket with status='SystemError: invalid certificate chain', was_clean='false'
Sync: Connection[1]: Connection closed due to error

Where is the getUserItems defined?

I am trying to figure out how the flexible sync works, and when I am looking at this code:

Realm initRealm(User currentUser) {
  Configuration config = Configuration.flexibleSync(currentUser, [Item.schema]);
  Realm realm = Realm(
    config,
  );
  final userItemSub = realm.subscriptions.findByName('getUserItems');
  if (userItemSub == null) {
    realm.subscriptions.update((mutableSubscriptions) {
      // server-side rules ensure user only downloads own items
      mutableSubscriptions.add(realm.all<Item>(), name: 'getUserItems');
    });
  }
  return realm;
}

I am wondering, where is the getUserItems is defined? I can't find in the codebase: the https://github.com/mongodb/template-app-dart-flutter-todo.git
