K6 can not resolve imports in siblings of parent directory

[jeroenhuinink]

Brief summary

K6 does not resolve imports in siblings of the parent directory.

The following is the minimal reproduction:

• create a file: 1/test.ts that imports a function from 2/lib.ts.
• from the root directory (the one containing dirs 1 and 2) run the command: k6 run 1/test.ts then the script starts and runs as expected.
• when you go into directory 1 and run the command k6 run test.ts you get the following error:

ERRO[0000] Automatic extension resolution is enabled but it failed to analyze the dependencies. Please, make sure to report this issue by opening a bug report.  error="test.ts:1:20 opening file via launcher's bridge: open 2/lib.ts: Het systeem kan het opgegeven pad niet vinden."
ERRO[0000] test.ts:1:20 opening file via launcher's bridge: open 2/lib.ts: Het systeem kan het opgegeven pad niet vinden.

The error message in dutch Het systeem kan het opgegeven pad niet vinden. means The system can not find the file specified.

This bug was introduced in 1.2.3. It works in 1.2.2.

k6 version

1.2.3

OS

Windows 11

Docker version and image (if applicable)

No response

Steps to reproduce the problem

• create a file: 1/test.ts that imports a function from ../2/lib.ts.
  E.g.:

import { lib } from '../2/lib.ts';

export default function () {
    lib();
    console.log('test');
}

export function lib() {
    console.log('lib');
}

• go to directory 1 and run k6 run test.ts from the commandline.

Expected behaviour

k6 resolves the dependencies and runs the script.

Expected output:

Hi @jeroenhuinink 👋🏻

Thanks for reporting this 🙇🏻

I've just given it a try, and I'm unable to reproduce. It doesn't mean there is no bug, but it might not strictly be related to resolving imports, and, based on the module resolution error, rather about native extensions support.

Does any of your test rely on an extension (xk6-*) by any chance?

If so, would you be able to provide us an anonymized expanded example that illustrates the issue?

Bringing @pablochacin into this conversation too as he has been handling most of the module/extension resolution in k6; any hunch on this?

[pablochacin]

Hi @jeroenhuinink, I'm unable to reproduce the error.

I'm assuming that this code is the content of 2/lib.ts, right?

export function lib() {
    console.log('lib');
}

Following your instructions, I get this result:

INFO[0000] lib                                           source=console
INFO[0000] test                                          source=console

[AndrewASel]

Hello, we have same errors, this is an example of lib (Test.js)

class TestClass {
    constructor() { }
    static lib() {
        console.log('lib');
    };
};

export { TestClass };

In K6 test
import { TestClass } from "../../../Common/Test.js";

In version 1.3 this errors appears:
ERRO[0000] Automatic extension resolution is enabled but it failed to analyze the dependencies. Please, make sure to report this issue by opening a bug report. error="../../K6tests/SomeTest.js:2:26 opening file via launcher's bridge: open ..//Common/Test.js: The system cannot find the path specified."
It works fine in version 1.2.2

The structure looking like this

Common
   Test.js
Apis
    Tests
  	   K6tests
	       SomeTest.js

[mstoykov]

I still can not reproduce this.

I have created a repo https://github.com/mstoykov/k6-issue-5176 - can you please check it out and test that this oversimplified example works for you? And if it does, can you try to make it not work in v1.3.0?

Thank you for your time 🙇

• I get the error when I run the command from the Apis directory, but not when I run if from the root of the repo. When I run it with version 1.2.2 I also do not see the problem.
• The error only occurs when I run it on Windows. I tested the same on WSL (under Ubuntu) and did not get the error there.

[mstoykov]

@jeroenhuinink can you rename your binary to k6 and run it like that. I think that it doesn't work in v1.2.2 as well.

Can you also confirm the same for v1.2.1 ?

[jeroenhuinink]

Unexpected result: I can reproduce the error with k6 1.2.3 and k6 1.2.1, but not with k6 1.2.2. See below:

[mstoykov]

Thank you again for all the info.

With help from @pablochacin and @andrewslotin we were able to reproduce it locally and have a fix in #5206

Can both of you please try the binaries build from that PR from https://github.com/grafana/k6/actions/runs/17981261227 and see that this fixes your concrete cases as well?

[jeroenhuinink]

Yes, can confirm that the binary from the PR solved my concrete case. Thanks!
