vite-express: production build on Netlify keeps failing

Hi, I’m setting up vite-express for the first time. This is what the script block in my package.json looks like:

  "scripts": {
    "dev": "vite",
    "build": "tsc && vite build",
    "lint": "eslint . --ext ts,tsx --report-unused-disable-directives --max-warnings 0",
    "preview": "vite preview"
  },

And, here’s my server file.

import express from "express";
import ViteExpress from "vite-express";

export const app = express();

ViteExpress.config({
 mode: "production",
});

ViteExpress.listen(app, 5173, () => console.log("Server is listening..."));

In my build logs, I keep getting “tsc: not found”. Whenever I go ahead remove tsc from the command in package.json, and I’d get vite: not found.

What could be wrong? For context; here’s an excerpt of what the error looks like:
