Unable to edit message when updating a message to CV2 with embeds set to null

[BrammyS]

Description

According to the docs you should be able set the IS_COMPONENTS_V2 flag on an old message. It states that the embeds, content, etc, need to be set to null.

This seems to only work with content. Setting this to null does allow the message to be edited while using the new flag. However, embeds, sticker_ids and files don't seem to work when being set to null. It does work when they are set to [].

Steps to Reproduce

### Create a message
POST https://discord.com/api/v10/channels/1111111/messages
content-type: application/json
Authorization: Bot xxxxxx

{"embeds":[{"title":"Testing","description":"Test"}]}

### Edit a message
PATCH https://discord.com/api/v10/channels/1111111/messages/11111111
content-type: application/json
Authorization: Bot xxxxxx

{
    "embeds": null,
    "flags": 32768,
    "components": [
        {
            "type": 17,
            "components": [
                {
                    "type": 10,
                    "content": "Test"
                }
            ]
        }
    ]
}

Expected Behavior

An old message that includes embeds can be edited to a message that uses IS_COMPONENTS_V2 when setting the embeds field to null.

Current Behavior

The API returns a 400 BAD REQUEST.

This looks like a documentation issue since the proper type is [] not null as embeds is an array

I wasn't sure because it did work on content even though that is not mark as nullable as well.
