Realm sync not working for embedded objects in react native - react-native

Question

This is my collection schema on realm -
{
"title": "testnote",
"properties": {
"_id": {
"bsonType": "objectId"
},
"_syncPartition": {
"bsonType": "string"
},
"title": {
"bsonType": "string"
},
"description": {
"bsonType": "string"
},
"subject": {
"bsonType": "string"
},
"tags": {
"bsonType": "array",
"items": {
"bsonType": "string"
}
},
"pages": {
"bsonType": "array",
"items": {
"title": "notespage",
"bsonType": "object",
"properties": {
"type": {
"bsonType": "string"
},
"data": {
"bsonType": "string"
}
}
}
},
"createdBy": {
"bsonType": "string"
}
}
}
This is how I've declared realm schema in react native. The code to initialize the Realm connection is also added below.
static NotesPage = {
name: "notespage",
embedded: true,
properties: {
type: "string",
data: "string"
}
}
static mainSchema = {
name: "testnote",
properties: {
_id: "objectId?",
_syncPartition: "string?",
createdBy: "string?",
title: "string?",
description: "string?",
subject: "string?",
tags: "string[]",
pages: { type: "list", objectType: "notespage" }
},
primaryKey: "_id"
};
const sampleNotesConfig = {
schema: [mainSchema NotesPage],
sync: {
user,
partitionValue: notesPartition,
newRealmFileBehavior: OpenRealmBehaviorConfiguration,
existingRealmFileBehavior: OpenRealmBehaviorConfiguration
}
};
Realm.open(sampleNotesConfig).then((notesRealm) => {
//// Some relevant code
}).catch((reason) => {
console.log("Error initializing realm");
console.log(reason);
});
When I create the realm object, it gets inserted in the local realm file but never gets synced to the server. I don't see any server errors or errors in local.
notesRealm.write(() => {
notesRealm.create(
SampleNote.schema.name,
{
"subject": "History",
"title": "Local to Remote Note 10",
"description": "Local to Remote Note 10 Description",
"tags": ["Tag 1", "Tag 2", "Tag 3"],
"pages": [{"type": "COVER_PAGE", "data": "Data 1"}, { "type": "PARAGRAPH", "data": "Data 2"}]
});
});
I have checked following things -
Partition values are correct.
User has permission to read/write to that partition.
If I just remove the pages section from the schema, the object starts syncing.
