如何用MongooseIM GraphQL API更新用户MUC房间附属关系？权限问题求助

环境信息 #

• MongooseIM版本：6.2.1
• 安装来源：官方Docker镜像
• Erlang/OTP版本：25

复现步骤 #

1. 以管理员身份创建用户A、B（操作成功）

mutation register_user {
    account {
        registerUser(
            domain: "DOMAIN"
            password: "PASSWORD"
            username: "USER-A/USER-B"
        ) {
            jid
            message
        }
    }
}

2. 以用户B身份创建MUC房间（操作成功）

mutation create_room {
  muc {
    createInstantRoom(
      nick: "USERNICK",
      room: "ROOM_NAME@group.host"
    ) {
      jid
      title
      private
      usersNumber
    }
  }
}

3. 以用户B身份更新MUC房间属性（操作成功）

mutation change_room_configuration {
    muc {
        changeRoomConfiguration(
            room: "_store@group.localhost"
            config: {
                title: "TITLE"
                description: "DESCRIPTION"
                allowChangeSubject: true
                allowQueryUsers: true
                allowPrivateMessages: true
                allowVisitorStatus: true
                allowVisitorNickchange: true
                public: true
                publicList: true
                persistent: true
                moderated: false
                membersByDefault: true
                membersOnly: false
                allowUserInvites: true
                allowMultipleSession: true
                passwordProtected: false
                password: null
                anonymous: false
                mayGetMemberList: ["member"]
                maxUsers: 30
                logging: true
            }
        ) {
            title
            description
            allowChangeSubject
            allowQueryUsers
            allowPrivateMessages
            allowVisitorStatus
            allowVisitorNickchange
            public
            publicList
            persistent
            moderated
            membersByDefault
            membersOnly
            allowUserInvites
            allowMultipleSession
            passwordProtected
            password
            anonymous
            mayGetMemberList
            maxUsers
            logging
        }
    }
}

4. 将用户A添加到MUC房间并设置附属关系为MEMBER（操作失败）

# 以用户B身份在GraphiQL中调用（失败）
# 以管理员身份在GraphiQL中调用（失败）
mutation muc {
  muc {
    setUserAffiliation(
      affiliation: MEMBER,
      room: "desired-muc@group.localhost",
      user: "user-a@localhost"
    )
  }
}
