PUT Object Issues

[rootelement]

In dev, trying to update this object:
717f514d-f375-4e25-aff9-07d2af3052e2

The object looks like this:

{
        "ssoId": "",
        "createdAt": "2018-09-27T14:37:55.000Z",
        "selfRegister": false,
        "createdBy": "8547899",
        "domain": "",
        "name": "Zurich - Parent Group",
        "privateGroup": true,
        "id": "717f514d-f375-4e25-aff9-07d2af3052e2",
        "oldId": "20000145",
        "status": "active"
 }

There is no description property. If i omit it for a PUT, i get a 400 error:
[1] "description" is not allowed to be empty
If i force it to be an empty string, i get the same error.

This is the cURL i'm trying to use:

curl --location --request PUT 'https://api.topcoder-dev.com/v5/groups/041e0be4-7599-402f-989b-b2873b0bed7e' \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer [DEV_GROUPS_M2M]' \
--data-raw '{ selfRegister: false,
  domain: 'zurich-competitors',
  name: 'Zurich - Competitors',
  privateGroup: true,
  oldId: '20000226',
  status: 'active'}'

In this case, I also stripped ssoId, it wouldn't let me write that back as empty, but it's empty as it is now.
