解决办法：
找到文件：app/services/agent/AgentLevelServices.php 214~247行
替换getAgentLevelBrokerage方法的代码为

public function getAgentLevelBrokerage(int $uid, $userInfo = [])
    {
        $one_brokerage_up = $two_brokerage_up = $spread_one_uid = $spread_two_uid = 0;
        if (!$uid) {
            return [$one_brokerage_up, $two_brokerage_up, $spread_one_uid, $spread_two_uid];
        }
        //商城分销是否开启
        if (!sys_config('brokerage_func_status')) {
            return [$one_brokerage_up, $two_brokerage_up, $spread_one_uid, $spread_two_uid];
        }
        /** @var UserServices $userServices */
        $userServices = app()->make(UserServices::class);
        if (!$userInfo) {
            $userInfo = $userServices->getUserInfo($uid);
        }
        if (!$userInfo) {
            return [$one_brokerage_up, $two_brokerage_up, $spread_one_uid, $spread_two_uid];
        }
        //获取上级uid ｜｜ 开启自购返回自己uid
        $spread_one_uid = $userServices->getSpreadUid($uid, $userInfo);
        $one_agent_level = 0;
        $two_agent_level = 0;
        $spread_two_uid = 0;
        if ($spread_one_uid > 0 && $one_user_info = $userServices->getUserInfo($spread_one_uid)) {
            $one_agent_level = $one_user_info['agent_level'] ?? 0;
            $spread_two_uid = $userServices->getSpreadUid($spread_one_uid, $one_user_info, false);
            if ($spread_two_uid > 0 && $two_user_info = $userServices->getUserInfo($spread_two_uid)) {
                $two_agent_level = $two_user_info['agent_level'] ?? 0;
            }
        }
        $one_brokerage_up = $one_agent_level ? ($this->getLevelInfo($one_agent_level)['one_brokerage'] ?? 0) : 0;
        $two_brokerage_up = $two_agent_level ? ($this->getLevelInfo($two_agent_level)['two_brokerage'] ?? 0) : 0;
        return [$one_brokerage_up, $two_brokerage_up, $spread_one_uid, $spread_two_uid];
    }
