Group-Owned API Key doesn't seem to work with Open Cloud Inventory API

It appears to me that Group-Owned API Keys aren’t able to utilize the Open Cloud Inventory API.

When using a personal API Key (one created on my personal account’s creator dashboard), the API behaves as expected. However, when using an API Key created under a group, I get a strange response:

 status_code = 401,
  {
    "code": "UNAUTHENTICATED",
    "message": "Authentication type provided was invalid!"
  }

Both API Keys have the same permissions (user.inventory_item:read).

If anyone else has had this issue, would love to hear about it, as well as any solutions you guys came up with besides just making an API Key under your account. Thanks!

This may be a bug within Roblox’s Open Cloud APIs. You might want to consider reporting it in #bug-reports.

Unfortunately, I am not a part of the bug reporting group so I can’t post there. I applied but haven’t been accepted yet.
