Custom Database login script get “Request to Webtask exceeded allowed execution time”

Ready to post? :mag: First, try searching for your answer.
I’m trying to set up a custom database to my Azure SQL Database with whitelist setting up (as attached image), but when I “Save and Try” the following script, just get the “Request to Webtask exceeded allowed execution time”. Also tried to check the log or Real-time Webtask logs, not much details from there. Could help me find a solution? Thanks!

function login(email, password, callback) {
    //this example uses the "tedious" library
    //more info here: http://pekim.github.io/tedious/index.html
    const bcrypt = require('bcrypt');
    const sqlserver = require('tedious@16.2.0');
  
    const Connection = sqlserver.Connection;
    const Request = sqlserver.Request;
    const TYPES = sqlserver.TYPES;
  
    const connection = new Connection({
      userName:  configuration.userName,
      password:  configuration.dbPassword,
      server:    configuration.DBServer,
      options:  {
        database: configuration.dbName,
        encrypt: true // for Windows Azure
      }
    });
  
    const query = 'SELECT Id, UserName, Email, PasswordHash FROM dbo.AspNetUsers WHERE Email = @Email';
  
    connection.on('debug', function (text) {
      console.log(text);
    }).on('errorMessage', function (text) {
      console.log(JSON.stringify(text, null, 2));
    }).on('infoMessage', function (text) {
      console.log(JSON.stringify(text, null, 2));
    });
  
    connection.on('connect', function (err) {
      if (err) return callback(err);
  
      const request = new Request(query, function (err, rowCount, rows) {
        if (err || rowCount < 1) return callback(err || new WrongUsernameOrPasswordError(email));
  
        bcrypt.compare(password, rows[0][3].value, function (err, isValid) {
          if (err || !isValid) return callback(err || new WrongUsernameOrPasswordError(email));
  
          callback(null, {
            user_id: rows[0][0].value,
            nickname: rows[0][1].value,
            email: rows[0][2].value
          });
        });
      });
  
      request.addParameter('Email', TYPES.VarChar, email);
      connection.execSql(request);
    });
  }
