在 render.com 上部署失败，因为找不到自定义模块

Question

这是我在尝试部署本地站点时遇到的完整错误日志：

(node:64) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)

我必须在所有 api 路由上添加 try..catch，我已经仔细检查了文件路径是否正确。一切看起来都很好，我可以在本地运行网站没问题。
