            its workspace was deleted.

            - `unauthorized`: No `Authorization: Bearer` header, or an empty
            token.

            - `api_key_not_scoped`: A key issued without scopes was used outside
            `/v1`.

            - `api_key_owner_inactive`: The member the key acts for was removed
            or suspended.

            - `forbidden`: The key lacks the permission named in
            `requiredPermission`, or the resource belongs to another workspace.

            - `workspace_pending_approval`: The workspace has not been approved
            yet.

            - `workspace_suspended`: The workspace is suspended.

            - `internal_error`: An unexpected error. A `400` with this code
            usually means the body is not valid JSON; a `413` means the body is
            larger than 1 MB.
