Cannot attach files to an updated record

[lallulli]

I'm using Invenio 3.2. I create a new record using the REST API, POST method:

POST https://127.0.0.1:5000/api/records/

Say the new record gets id 1. Now I can attach files to the new record:

PUT https://127.0.0.1:5000/api/records/1/files/my_file.txt

The new file gets attached correctly. Later, I update my record using the PUT method:

PUT https://127.0.0.1:5000/api/records/1

Update is successful, but attached files disappear. If I try again to attach a file, I get a 404 error:

PUT https://127.0.0.1:5000/api/records/1/files/my_file_2.txt
{'message': 'The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.', 'status': 404}

This is because the record is getting cleared in the PUT endpoint

So the record with a file from this form

{
    "$schema": "https://my-site.com/schemas/records/record-v1.0.0.json",
    "id": "11",
    "title": "Sponge",
    "contributors": [{"name": "Bob"}],
    "_bucket": "dc6a4c08-0a18-48e8-90d1-3a4a3cb0958c",
    "_files": [
        {
            "key": "file.txt",
            "size": 13,
            "bucket": "dc6a4c08-0a18-48e8-90d1-3a4a3cb0958c",
            "file_id": "75f4058c-0347-427e-a398-6b62aa3e602f",
            "checksum": "md5:59ca0efa9f5633cb0371bbc0355478d8",
            "version_id": "7602c2ff-f318-48d4-8f55-b278ebfeb051"
        }
    ]
}

when we update our record with a new payload it becomes

{
    "$schema": "https://my-site.com/schemas/records/record-v1.0.0.json",
    "id": "11",
    "title": "Updated",
    "contributors": [{"name": "Name"}]
}

update: This will get fixed with the new core modules flask-resources and invenio-resources.
