开放平台设置了多个服务器域名，如a.xx.com;b.xx.com均不带https，然后调用modify_domain方法，设置小程序服务器域名

{
  "action": "add",
  "requestdomain": ["https://a.xx.com", "https://b.xx.com"],
  "wsrequestdomain": ["wss://a.xx.com"],
  "uploaddomain": ["https://a.xx.com", "https://b.xx.com"],
  "downloaddomain": ["https://a.xx.com", "https://b.xx.com"],
  "udpdomain": [],
  "tcpdomain": []
} 

返回结果是：

错误代码：85301,no domain to modify after filtered, please confirm the domain has been set in miniprogram or open, and follows the rule of domains

查阅文档，85301错误是：存在 “不符合域名规则的域名”导致无修改。

该如何处理？我的设置哪里有问题？
