Yammer DELETE group_memberships.json？group_id = [：id] API发送“ cannot_remove_last_admin”

Question

我尝试使用此API

DELETE https://www.yammer.com/api/v1/group_memberships.json?group_id=:group_id

端点发送以下响应：

status: 400
{
    "response": {
        "error_code": "cannot_remove_last_admin"
    }
}

尽管我也将其他用户设置为admin， 这个API如何运作？ https://developer.yammer.com/docs/group_membershipsjsongroup_idid-1
