我是一个新手，正在尝试使用Firebase函数与实时数据库（模拟器套件）一起使用。但是当我尝试使用Firebase函数设置数据库中的值时，它会出现错误并且无法将该值设置到数据库中。
错误：

I
function[us-central1-textToLength]
[2021-11-05T12:03:14.194Z] @firebase/database: FIREBASE WARNING: wss:// URL used, but browser isn't known to support websockets. Trying anyway.

Firebase函数代码：
const functions = require('firebase-functions');
var admin = require("firebase-admin");
admin.initializeApp();
var database = admin.database();
exports.helloWorld = functions.https.onRequest((request, response) => {
response.send("Hello from Firebase!");
});
exports.textToLength = functions.https.onRequest((request, response) => {
var tex = request.query.text;
var textLength = tex.length;
console.log(textLength);
database.ref().child('test').set("op");
response.send(String(textLength));
});
