Mosquitto动态安全插件无法添加用户/角色问题求助

使用Mosquitto 2.0.15版本的动态安全插件（Dynamic Security Plugin）时，无法添加任何用户或角色。执行命令mosquitto_ctrl -u myadmin dynsec createClient testUser无报错，设置完测试用户testUser的密码后，查看/opt/mosquitto/dynamic-security.json文件，仅能找到初始创建的myadmin用户。以下是相关操作日志及配置文件内容：

操作日志 #

ubuntu@instance-20220606-2142:~$ mosquitto_ctrl -u myadmin dynsec createClient testUser
请输入testUser的新密码。直接回车则不设置密码（用户将无法登录）。
输入testUser的新密码:
再次输入testUser的新密码:
警告：你正在未加密的环境下运行mosquitto_ctrl。
这意味着你所做的所有配置更改（包括密码）都会在网络上明文传输，存在泄露风险。

输入myadmin的密码:
