Expected Behavior

Typecheck runs without error

Actual Behavior

> typecheck
> react-router typegen && tsc

failed to load config from /{redacted}/my-react-router-app/vite.config.ts
Error [ERR_REQUIRE_ESM]: require() of ES Module /{redacted}/my-react-router-app/node_modules/p-map/index.js from /{redacted}/my-react-router-app/node_modules/@react-router/dev/dist/vite.js not supported.
Instead change the require of index.js in /{redacted}/my-react-router-app/node_modules/@react-router/dev/dist/vite.js to a dynamic import() which is available in all CommonJS modules.

This piece of granular code fixes the issue:

const import_p_map = await import('p-map');
await (0, import_p_map.default)(build.prerender, prerenderSinglePath, { concurrency });

Steps to fix

1. This file honey-ginger/node_modules/@react-router/dev/dist/vite.js has require import of ('p-map').
2. remove this import and change it to dynamic import , add the above code before this line await (0, import_p_map.default)(build.prerender, prerenderSinglePath, { concurrency });
3. This is able to run the project
