Hello! Trying to use BigInt, it works good during development, but when I'm trying to build it I have got this error:

⚙ Built your router server successfully

My config:

// app.config.ts
import tailwindcss from "@tailwindcss/vite";
import { defineConfig } from "@tanstack/react-start/config";
import type { PluginOption } from "vite";
import svgr from "vite-plugin-svgr";
import tsConfigPaths from "vite-tsconfig-paths";

export default defineConfig({
    vite: {
        plugins: [
            tailwindcss(),
            svgr(),
            tsConfigPaths({
                projects: ["./tsconfig.json"],
            }),
        ] as PluginOption[],
    },
});

Fixed by changing the constant 0n -> BigInt(0)
