nx run-many fails with ERROR: No cached ProjectGraph is available.

[just-be-weird]

Current Behavior

I'm facing a very annoying error in our project. I tried to replicate in a small POC and was able to reproduce it. The POC app is an express app with prisma client. Whenever I make any changes in the files the serve command fails and I've to run nx reset and then again run nx run many command to get around this. As our main project is quite huge it has become a big problem.

Expected Behavior

When we make any changes in the files it should run without any errors.

GitHub Repo

https://github.com/just-be-weird/emarket

Steps to Reproduce

1. Clone the repo
2. Install the dependencies
3. Comment out the routes code in services/auth/src/routes/auth.router.ts

import { Router } from 'express';

// import {
//   forgotPassword,
//   verifyUserForgotPassword,
// } from '../controller/forgot-password.controller';
// import { loginUserController } from '../controller/login-user.controller';
// import { resetPassword } from '../controller/reset-password.controller';
// import { userRegistrationController } from '../controller/user-registration.controller';
// import { verifyUserController } from '../controller/verify-user.controller';

const router: Router = Router();

// router.post('/login', loginUserController);
// router.post('/register-user', userRegistrationController);
// router.post('/verify-user', verifyUserController);
// router.post('/forgot-password-user', forgotPassword);
// router.post('/reset-password-user', resetPassword);
// router.post('/verify-forgot-password-user', verifyUserForgotPassword);

export default router;

4. run pnpm dlx prisma generate and pn dlx prisma db push
5. run pnpm dev
6. Now make any changes in let say services/auth/src/main.ts And check the logs of @emarket/auth serve command

This patch fixed the issue for me, but I have had trouble getting it in via pull request. Could you verify it fixes the race condition for you as well?

race-fix-core-b9bfeeb1d1..0aac22bbc8.patch

[just-be-weird]

@enki yes, I can give it a try. Is the patch based on main branch?

[enki]

Yes, but it's off an older version. I suspect it should still apply cleanly, but I haven't had the time to merge it forward continuously (our project is now stably running off an older patched version and we can't migrate forward until upstream accepts this or something similar that stops breaking our builds).
