将json数组导入Firebase和Firestore时出错

我使用这段代码将json数组导出到CloudFireStore

const admin = require("firebase-admin");
const serviceAccount = require("./service-key.json");
const data = require("./state.json");
admin.initializeApp({
    credential: admin.credential.cert(serviceAccount),
    databaseURL: "https://functionstest-54bd9.firebaseio.com"
});
data && Object.keys(data).forEach(key => {
    const nestedContent = data[key];
    if (typeof nestedContent === "object") {
        Object.keys(nestedContent).forEach(docTitle => {
            admin.firestore()
                .collection(key)
                .doc(docTitle)
                .set(nestedContent[docTitle])
                .then((res) => {
                console.log("Document successfully written!");
            })
                .catch((error) => {
                console.error("Error writing document: ", error);
            });
        });
    }
});

但当我运行这个时，我得到了错误

编辑

我的输入是一个json数组，错误很明显，然后我像这样更改了json文件

{"countries":[
    {
        "countryId" : 1,
        "countryName" : "Any",
        "phoneCode" : null,
        "sortName" : null
    },
    {
        "countryId" : 2,
        "countryName" : "India",
        "phoneCode" : null,
        "sortName" : null
    }
]
}

当我再次尝试时，我在控制台中得到了这个

Error writing document:  { Error: Missing or insufficient permissions.
    at /home/me/Documents/TfmFirebase/functions/node_modules/grpc/src/client.js:554:15 code: 7, metadata: Metadata { _internal_repr: {} } }

我已经添加了一个服务帐户，并在脚本中添加了json。这有什么不对？

我在创建服务帐户时忘记设置角色，删除了旧的服务帐户，使用编辑器角色创建了新的服务帐户，并在脚本中添加了新的json。现在它工作了

您编辑的最后一个json为我服务，谢谢。
