使用应用程序脚本更改 gsuite 签名 returns "isDefault cannot be toggled to false"

Question

正在尝试使用 Google Apps 脚本为用户设置签名。我已经设置了一个服务帐户并确保范围正确，但是当我测试代码时 returns 出现以下错误：

"error": { "errors": [ { "domain": "global", "reason": "invalidArgument", "message": "isDefault cannot be toggled to false" } ], "code": 400, "message": "isDefault cannot be toggled to false" } }

代码如下：

function setUserSignature() {
      var resource ={
  "sendAsEmail": "email@mycompany.be",
  "displayName": "Name Lastname",
  "replyToAddress": "email@mycompany.be",
  "signature": "Test Signature",
  "isDefault": true,
  "treatAsAlias": true
}


var service = serviceAccount("serviceaccount@mydomain.be");
service.reset();
if (service.hasAccess()) {
    var options = {
      "muteHttpExceptions":true,
"method":"PUT",
"headers": {"authorization": "Bearer " + service.getAccessToken()},
      "body":resource


}
        var url = 'https://www.googleapis.com/gmail/v1/users/'+ 'email@mycompany.be' +'/settings/sendAs/'+'email@alias.be';
        var response = UrlFetchApp.fetch(url,options);
        Logger.log(response.getContentText());
    }
}

如果其他人遇到同样的问题：

显然使用 PATCH 而不是 PUT 解决了这个问题。
