failed to read input source map - @swc/jest + yarn PnP workspaces

[mrginglymus]

Describe the bug

Using yarn PnP with workspaces causes swc to emit

  ERROR  failed to read input source map: failed to parse inline source map url
src.js.map

Caused by:
    relative URL without a base

Switching to the node-modules linker, stops the errors.

I'd been seeing this for a while, and hoped that #8789 might fix it, but it appears not to

Input code

// sub-package is a workspace package with a peer dependency
import adder from 'sub-package';

it('tests', () => {
    expect(adder(1, 2)).toEqual(3)
});

Config

export default {
    cache: false,
    transform: {
        "^.+\\.m?(t|j)sx?$": "@swc/jest"
    },
    testPathIgnorePatterns: ["/node_modules/"],
}

Expected behavior

No errors :)

Version

1.7.9

Additional context

This only happens when importing code from a workspace package with peer dependencies.

[mrginglymus]

Sigh. Closing because only after raising this issue I spot the error in my regex. However, hopefully someone else may see this issue and realise their regex is broken too.

[mrginglymus]

Re-opening as I've finally managed to get a minimal repro of the original issue I was facing relating to importing code from workspace packages with peer dependencies.

[davidmurdoch]

I've been seeing this issue since v1.4.12 :-(

[mrginglymus]

I see that #9422 suggests it may help with #8910, which is a duplicate of this issue (without a reproduction). I've tried 1.7.11, but I'm still getting the same error message, with no additional details:

  ERROR  failed to read input source map: failed to parse inline source map url
index.js.map

Caused by:
    relative URL without a base

[mrginglymus]

It still seems to be using swc-0.283.0 on 1.7.11, which surprised me.

[mrginglymus]

1.7.12-nightly-20240816.1 has swc-0.284.0 which does give us the improved errors:

ERROR  failed to read input source map: failed to find input source map file "index.js.map" in 
"C:\\Users\\<me>\\git\\<my-project>\\.yarn\\__virtual__\\<my-package>-virtual-c44221b7bd\\1\\packages\\baseline\\dist\\components\\icon\\index.js"
file as either "C:\\Users\\<me>\\git\\<my-project>\\.yarn\\__virtual__\\<my-package>-virtual-c44221b7bd\\1\\packages\\baseline\\dist\\components\\icon\\index.js.map" 
or with appended .map

I can confirm that said file does exist (in packages/baseline/dist/components/icon/index.js.map), so something in swc is failing to resolve Yarn's virtual package folder

I am facing the same issue but with pnpm's default settings (through Jest)

Here's a reproduction:

Can you update @swc/core of your repro? It should be v1.7.14

[Zulqarnain-ZQ]

I have updated @swc/core to v1.7.18 but issue still persists

[ziimakc]

Same issue with pnpm workspaces , source maps are present.

[aminya]

Now, I have more information in the latest release of swc. For me, the error is actually coming from one of the dependencies that doesn't have the source map in the package.

  ERROR  failed to read input source map: failed to find input source map file "index.js.map" in "/Users/runner/work/setup-cpp/setup-cpp/node_modules/.pnpm/[email protected]/node_modules/ubuntu-version/index.js" file as either "/Users/runner/work/setup-cpp/setup-cpp/node_modules/.pnpm/[email protected]/node_modules/ubuntu-version/index.js.map" or with appended .map

[ruscon]

with docker + pnpm workspace and

    "@swc/cli": "0.4.0",
    "@swc/core": "1.7.24",

an error

ERROR  failed to read input source map: failed to read input source map
                               from file at packages/api/src/bootstrap.js.map

Plus in my case I can already have compiled js files and swc adds sourceMappingURL comment after each compilation without check if it is already exists.

 //# sourceMappingURL=bootstrap.js.map
