Error in inside a function: The document data and permissions are missing

I'm trying to update a document in a function with this code:

const document_data = {
  tipo: data.markin.type,
  updated_at: DateTime.now().toISO(),
};

const marking = await databases_user.updateDocument(
  DB_RH,
  C_MARKIN,
  data.marking.$id,
  document_data
);

The functions fails with the error: AppwriteException: The document data and permissions are missing. You must provide either document data or permissions to be updated.

So I logged document_data and I see the data is there before I send it with updateDocument

Then I have replaced the databases.php in the appwrite source code to add some debug logs, I can see the following information when the request is make:

appwrite  | string(2) "db" // $databaseId
appwrite  | string(10) "collection" // $collectionId
appwrite  | string(2) "id" // $documentId
appwrite  | array(0) { // $data
appwrite  | }
appwrite  | NULL // $permissions

So seems like the problem is the SDK not sending the data. But when I try the same function running it with the CLI it works without problem

I'm using:

• appwrite 1.6.0
• node-appwrite 14.1.0
• bun 1.0

What can be happening?
