The "from" argument must be of type string. Received type undefined

[stefdelec]

I am trying to use steps I wrote and publish on npm
Here is the error I have:

> cucumber-js e2e/src/**/*.feature --require ./node_modules/@myProject/uat/dist/*.step.js

TypeError [ERR_INVALID_ARG_TYPE]: The "from" argument must be of type string. Received type undefined

I have found that this is this.cwd which is undefined. What can i do?

If I copy paste my steps in the root directory (where the package.json is), I don't have any error. So the problem is: I cannot not --require from node_modules.

[jonathanwork]

did you try from node_modules in your local directory ?

[VivekLande]

any resolution for this issue? I am getting this error with Cucumber 7

[davidjgoss]

@stefdelec @VivekLande this is likely related to either

• your steps package depending on a different version of cucumber than your host project
• working locally with your steps package npm link'd

In either case you can end up with two different cucumber-js instances at runtime which can cause this (you could check this by looking in your node_modules hierarchy).

I'm working on documenting this in #1540 - take a look at the workaround and see if that works for you?

[VivekLande]

Thanks @davidjgoss, I am able to resolved the issue with the solution provided by you.

[csurfleet]

This workaround isn't working for me. I've definitely not got cucumber installed elsewhere. I've been on this for hours and I'm getting nowhere. This is my package json dependencies:

"dependencies": {
    "@cucumber/cucumber": "^7.0.0",
    "@cucumber/cucumber-expressions": "^12.0.0",
    "gherkin-testcafe": "^5.0.0",
    "testcafe": "^1.13.0"
  }

I've searched my node_modules folder and cucumber isn't in there multiple times. I've no idea where to go next

[charlierudolph]

@csurfleet can you please create a minimal reproducible example?

[phatNfqAsia]

In my case,
Import a cucumber step-implementation module in a normal es module file (e.g index.ts) will lead to error: TypeError [ERR_INVALID_ARG_TYPE]: The "from" argument must be of type string. Received undefined
So the solution is to extract the logic and export normal functions from a different non-cucumber-related file

[aurelien-reeves]

@phatNfqAsia could you please give more info on your issue?
You seem to mention modules: are those EcmaScript modules?
What are your depenencies and versions? Would you have a repo where you would reproduce that issue with a minimal setup?

[phatNfqAsia]

@aurelien-reeves my repo is kept private so I can not share, sorry :(
My issue is when I am trying to call some API of @cucumber/cucumber with ts-node instead of cucumber-js command.
In fact I don't need to use it, the program throw error because I accidentally import one file that refer to that cucumber package.
So I detach the logic inside the to-import file, make sure it does not contain any cucumber reference and then my code start working.

[aurelien-reeves]

Ok, thanks for the details.

When I asked for a repo, that could be a reproduction repo made simple without confidential data. As simple as possible to reproduce the issue

[vcardins]

Wondering why this issue was closed. Still happening

[aurelien-reeves]

As requested before, would you have a minimal reproducible example?
That would help us helping you with this issue

https://github.com/cucumber/cucumber-js/blob/HEAD/docs/transpiling.md Did you try this?

For us, the above link was not the solution. We removed the package.json and node modules from the bdd test folder, and imported everything from the ''general'' package.json. Why it now works is still a mystery to me (since other folders in our project have their own package.json without issues) but figured it might help others to mention this here.
