Issue using @swc-node/register and @swc/core

[kris-vista]

Current Behavior

To avoid getting wanings from nx whenever I run a build, I have installed @swc/core, @swc-node/register and @swc/helpers
No however, whenever I run a build of one of my projects inside my nx monorepo, I get the following error

  ERROR  failed to read input source map: failed to parse inline source map url
",u=a.length,l=(0,dr.basename)(e),f=(0,dr.extname)(e),p=n(e),y=l.slice(0,-f.length)+p+".map",E=u+y.length;if(t.substr(-E,u)===a)return t.slice(0,-E)+o;let g=u+encodeURI(y).length;return t.substr(-g,u)===a?t.slice(0,-g)+o:`${t}

    at C:\Users\runneradmin\.cargo\registry\src\index.crates.io-6f17d22bba15001f\swc-0.272.4\src\lib.rs:385

The code that this error is referring to is located in .nx\cache\cloud\2402.27.3.hotfix2\index.js

While it says this is an error, the build appears to go through and complete successfully anyway

I have tried reinstalling my node_modules and removing the .nx folder but I get the same issue

I have tried creating a brand new nx monorepo with an empty app and this appears to build fine without this error.

Expected Behavior

The build should complete without any errors

Steps to Reproduce

I am unable to reproduce this outside of my complex monorepo

Nx schematics adds these two packages, and after install, build of angular is broken.

I have some custome executors so that would make sense

[dsimon-dev]

Upgrading NX to 18.1.2 fixed this issue for me.

[kris-vista]

I just upgraded to 18.1.2 and continue to get the same issue :(

[kris-vista]

I have managed to reproduce the issue with a brand new nx workspace.
Basically I created an angular nx workspace with a single app
I then created a plugin following the example here: https://nx.dev/extending-nx/recipes/local-executors

The repo can be found here
https://github.com/kris-vista/nx-swc-issue

When you have it all set up, running the following command will generate the error
nx run first:echo

Confirmed, exactly what I did too. Followed the instructions and got the same error, although the executor does work. Using version 18.2.1:

[JacobGardos]

After spending a couple hours debugging the nx bin, I've found a solution.

Simply install nx-cloud as a dependency.

npm install nx-cloud

I've tested it on Windows 11 and WSL via devcontainers and the problem seems to be fixed.

Here is a link to a basic working repository using a local plugin & executor:
https://github.com/JacobGardos/nx-swc-fix
(See README.md for instructions)

Let me know if this helps.

---

In case anyone is curious, here are some observations I made while debugging the nx run command using the Visual Studio Code JavaScript debugger. Hopefully, this can save you some time if you're attempting to implement a more permanent solution:

1. If you don't already have nx-cloud installed, the problem can also be resolved by solely using the local cache. In other words, if you remove the nxCloudAccessToken from your nx.json or environment variables, the error seems to go away.

2. If you don't have nx-cloud installed, when you debug the run command (e.g., nx run <project>:<target>), you'll notice that nx eventually calls a function inside of node_modules/nx/src/task-runner/run-command.js named loadTasksRunner(modulePath). From what I understand, this function checks to see if the nx-cloud package is installed. If it is, everything proceeds without issue. However, if nx-cloud is not installed, it seems to import a fallback package from its own directory at ../nx-cloud/nx-cloud-tasks-runner-shell. This might be where the error originates:

// node_modules/nx/src/tasks-runner/run-command.js  - line 261
function loadTasksRunner(modulePath) {
    try {
        const maybeTasksRunner = require(modulePath);
        // to support both babel and ts formats
        return 'default' in maybeTasksRunner
            ? maybeTasksRunner.default
            : maybeTasksRunner;
    }
    catch (e) {
        if (e.code === 'MODULE_NOT_FOUND' &&
            (modulePath === 'nx-cloud' || modulePath === '@nrwl/nx-cloud')) {
            return require('../nx-cloud/nx-cloud-tasks-runner-shell')
                .nxCloudTasksRunnerShell;
        }
        throw e;
    }
}

Hopefully, this helps. Let me know if I missed anything.

Can confirm this happened in a relatively new workspace, ~1 month or so, that has no Angular.

Connected workspace to Nx Cloud thinking it was the cache, but that solely did not fix the issue. It was not until I npm i nx-cloud as @JacobGardos suggested that the issue went away.

[blackholegalaxy]

We added nx-cloud as dependency without the issue being fixed. The error is still occuring since about 1 month.
