Node.js本地正常运行，Docker环境下出现模块找不到问题

问题已解决，感谢@DavidMaze，修复提交记录：f240a30006a8af0e4886565f0f86bda35a4bce05

问题现象 #

更新Discord Bot后出现异常：仅Docker环境中触发模块找不到错误，本地运行完全正常。本地与Docker环境的Node.js版本及依赖完全一致，使用Docker入口脚本运行结果相同。问题始于提交69c0d99c85142d77148faeeac32347f7906ee51e。

Error: Cannot find module '../database/birthdayCheck.js'

相关代码逻辑 #

index.js中的事件加载逻辑 #

// bot events handler
const eventsPath = path.join(__dirname, 'events');
const eventFiles = fs.readdirSync(eventsPath).filter(file => file.endsWith('.js'));

for (const file of eventFiles) {
    const filePath = path.join(eventsPath, file);
    const event = require(filePath);
    if (event.once) {
        bot.once(event.name, (...args) => event.execute(...args));
    } else {
        bot.on(event.name, (...args) => event.execute(...args));
    }
}

events/birthdayStatusChange.js中加载模块的代码 #

const { isBirthdayCheckedToday, setLastBirthdayChecked } = require('../database/birthdayCheck.js');

被加载的database/birthdayCheck.js文件确实存在于项目根目录下的database文件夹中。

期望结果 #

Bot能在Docker环境中正常运行，解决模块找不到的问题。
