Hapi response doesn't show tree-like (nested) json - json

Question

Ok, so I have an object that has the following structure:
interface FolderWithContent {
uuid: string
name: string;
folders: Array<FolderWithContent>;
files: Array<Files>;
}
Where Files is an extension of Sequelize.Model.
And I'm trying to return it with hapi (return h.response(tree).code(200);) (tree is my object, of course)
The thing is, my object has several levels and the response is only showing the root and 1st level. So if I have
{
"name": "folder1.1",
"uuid": "1",
"folders": [
{
"name": "folder2",
"uuid": "3986b8ca-314c-4ba8-b47c-9baa29ca7adc"
},
{
"name": "folder2.6",
"uuid": "7ff93401-1281-419c-9541-fb859c4e79e1",
"folders": [
{
"name": "folder3.1",
"uuid": "8d76aa76-fa42-40c6-9c46-9fa26c6b555c"
}
],
"files": [
{
"name": "file5",
"uuid": "9a8c9aa2-23bd-45e3-bb43-ddf0e085b066"
}
]
}
],
"files": [
{
"name": "file2.2.2",
"uuid": "88519cec-b19a-4e12-9138-6273ac66ba76"
},
{
"name": "file1",
"uuid": "9eb5235d-9d04-494d-845c-4a9780bc9687"
}
]
}
I will not get folders and files inside of folder2.6.
I have tried to return tree.folders[2], but it still only shows the folder name and uuid. However, if i return tree.folders[2].folders, only then it shows me the folders and files inside folder2.6.
I have tried calling Json.stringfy(tree) but it also has the exact same problem.

I still don't know WHY I had the problem, but I'm posting the way I found to fix it.
Turns out the issue was with sequelize. All the objects were models from sequelize. Converting the objects to simple JSONs did it for me.
tree.folders = content.folders?.map((folder) => {
return {
name: folder.name,
uuid: folder.uuid,
updated_at: folder.updated_at,
synced: folder.synced,
folders: [],
files: []
};
});
tree.files = content.files?.map((file) => {
return {
name: file.name,
uuid: file.uuid,
updated_at: file.updated_at,
synced: file.synced
};
});
