eslint未检测到解构变量

Question

我有以下代码：

    for ([uri, { socket, settings }] of map) {

        // parse websocket urls
        let url1 = new url.URL(ws.url);
        let url2 = new url.URL(uri);

        // override http(s) with ws(s)
        url2.protocol = url1.protocol;

        console.log(`Bridge "%s" <-> ${socket}://${host}:${port}`, url2);

        bridge(url2, settings, socket);

    }

哪些解构变量，但是ESLINT并未检测到变量：

/home/.../handler.js
  81:11  error  'uri' is not defined       no-undef
  81:18  error  'socket' is not defined    no-undef
  81:26  error  'settings' is not defined  no-undef
  85:32  error  'uri' is not defined       no-undef
  90:40  error  'socket' is not defined    no-undef
  90:52  error  'host' is not defined      no-undef
  90:60  error  'port' is not defined      no-undef
  92:22  error  'settings' is not defined  no-undef
  92:32  error  'socket' is not defined    no-undef

✖ 9 problems (9 errors, 0 warnings)

如何告诉linter linter的良好和变量被正确检测到？

.eslintrc.json

{
    "env": {
        "node": true,
        "commonjs": true,
        "es2021": true
    },

            "error",
            "double",

                "allowTemplateLiterals": true
            }
        ]
    }
}

对于循环需要const，（const ）

const map = [
  [
    "uri",
    {
      socket: "",
      settings: ''
    },
  ],
];

for (const [uri, { socket, settings }] of map) {
    console.log(uri, socket, settings);
}
