question

Just to expand on this with a hard example.

We have an item group in Clover:

{
    "attributes": {
        "elements": [
            {
                "id": "89QJTP2WAENYG",
                "itemGroup": {
                    "id": "0K0JYMJ4GJVKG"
                },
                "name": "Variant"
            }
        ]
    },
    "id": "0K0JYMJ4GJVKG",
    "items": {
        "elements": []
    },
    "name": "Standard Round Bend Treble"
}

As you can see from above, the item has an option with attribute_id

89QJTP2WAENYG

and the item group also has this attribute on it.

However, the item does not belong to the item group? I thought this is not possible, but here it looks like on the Clover side this item was once part of this group and now it is not. Shedding any light on this would be much appreciated.

Also, any attempts to re-associate the item with the group fail. If I go at it from the item group side, there is no error but nothing happens:

>>> pp(payload)
{
    "items": [
        {
            "id": "5RBQ01FBHGH56"
        }
    ],
    "name": "Standard Round Bend Treble"
}
>>> p.client.update_itemgroup('0K0JYMJ4GJVKG', payload)
{'id': '0K0JYMJ4GJVKG', 'name': 'Standard Round Bend Treble'}

If I go at it from the item side I get the error:

{"message":"Existing item cannot be added to item group"}

Again, please advise as this is causing a lot of sync issues for us currently and I don't know how things got in this state.

Much appreciated,
