Requirements.json specifying CustomObjects v2

In one of my apps I’m trying to have the app create 2 custom objects (v2). To do that I’m including a requirements.json file in my app and specifying the creation of the 2 objects. When you use custom objects by default 2 standard fields get created, Name and ExternalId. The issue I am running into is that when I try to specify the autoincrement settings for Name or add a description for ExternalId the app fails to install. I’m assuming because the custom object believes I’m asking for a duplicate field to be set where as all I’m trying to do is set the autoincrement on the Name and a description on the ExternalId. Things that I can easily do in the UI but since this is an app I cannot go the UI route.

I have code similar to this:

{
    "custom_objects_v2": {
        "objects": [
            {
                "key": "object_1",
                "include_in_list_view": false,
                "title": Object 1",
                "title_pluralized": "Object 1",
                "description": "object 1 description"
            },
            {
                "key": "object_2",
                "include_in_list_view": false,
                "title": Object 2",
                "title_pluralized": "Object 2",
                "description": "object 2 description"
            }
        ],
        "object_fields": [
           {
                "object_key": "object_1",
                "key": "standard::name",
                "title": "Name",
                "type": "text",
                "properties": {
                    "autoincrement_enabled": true,
                    "autoincrement_prefix": "Name1-",
                    "autoincrement_padding": 9,
                    "autoincrement_next_sequence": 1
                }
            },
            {
                "object_key": "object_1",
                "key": "standard::external_id",
                "title": "External ID",
                "description": "I want to add a description",
                "type":"text"
            },
            {
                "object_key": "object_2",
                "key": "standard::name",
                "title": "Name",
                "type": "text",
                "properties": {
                    "autoincrement_enabled": true,
                    "autoincrement_prefix": "Name2-",
                    "autoincrement_padding": 9,
                    "autoincrement_next_sequence": 1
                }
            },
            {
                "object_key": "object_2",
                "key": "standard::external_id",
                "title": "External ID",
                "description": "I want to add a description",
                "type":"text"
            },
 {
                "object_key": "object_2",
                "key": "field 1...n",
                "title": "Field 1 ...n",
                "description": "all the other fields represented ad this single object.",
                "type":"text"
            }
        ],
        "object_triggers": []
    }
}

The error I get when trying to install:
Custom objects install failed: Mysql2::Error: Duplicate entry '26585059-standard::name-CustomObject-\x01\x9FNE\xDA\xDF\xA2Mt\xC' for key 'cf_fields.account_key_owner_co'

You can replace standard::name with standard::externalid if you remove the Name fields but leave the ExternalId ones.

Now if I remove the Name and ExternalId fields from the requirements.json completely the install works as it should. but that doesn’t get me to where I need to be.

So the question is, within the requirements.json how would I enable autoincrement on the name field and possibly add a description to the externalId field. Not having the description on the externalId is not the end of the world but I would like to have both if possible.

Thanks in advance!
