Heroku 应用程序每六个小时运行一次，如何让它每天运行一次？

问题描述

我的 Heroku 应用程序应该每天发送一次电子邮件，但每六个小时发送一次电子邮件。我已添加并配置 Heroku 调度程序，使其在 UTC 每天下午 2:00 运行，但出于某种原因，该应用程序继续每六小时运行一次。

这与“一次性 Dynos”有关吗？

这是我的 procfile 的内容：

web: node js/scraper.js

这是我的代码。

const realtor = require("realtorca");
const unirest = require("unirest");
const nodemailer = require("nodemailer");
const { staticMapUrl } = require("static-google-map");
