[BUG] npm login - Exit handler never called!

[DanielLey21]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

When trying to run npm loginto authenticate with my companies artifactory in order to run npm install, I am unable to login, and the following error message is shown

$ npm login
npm notice Log in on https://artifactory.{companyname}.com/artifactory/api/npm/et-npm/
Login at:
https://artifactory.{companydomain}/ui/auth-provider/npm?uuid={id}
npm error Exit handler never called!
npm error This is an error with npm itself. Please report this error at:
npm error https://github.com/npm/cli/issues
npm error A complete log of this run can be found in: D:\Users\etc

Expected Behavior

I am expecting to be logged in, or the web browser for our artifacory is prompted so that I am authenticated. Then I can npm install correctly

Steps To Reproduce

I cannot provide those details.

Environment

• npm: 10.8.1
• Node.js: 20.12.2
• OS Name: Windows

HI @DanielLey21
To better understand the issue, could you please provide your npm config details. Please make sure to mask any sensitive information. you can replace sensitive information by [MASKED] or ***.

This will help to reproduce the issue and investigate further.

Hi. 👋 In case it helps, I've been running into this too. Here's my details:

Configuration

init-author-name=Brooke Kuhlmann
init-license=Hippocratic-2.1
progress=false
save-prefix=~
//registry.npmjs.org/:_authToken=<redacted>

System

• OS: macOS 14.5
• Node: 22.4.1
• Browser: Firefox

The workaround I've found is not to hit ENTER when problem occurs but, instead, copy the URL and paste it directly into your browser. This seems to complete authentication properly. ...but if you do hit enter, you'll always get the error reported above.

[kchindam-infy]

@bkuhlmann Thanks for the npm config, ofcourse i have tried with similar config with npm registry and authToken. On npm login command on Press Enter key it successfully launched the npmjs browser with login page as expected. Please check your config registry and try again.

Tried on:
OS: macOS 14.5
Node 20 and 22

[bkuhlmann]

Thanks. OK, I think I've got better Steps to Recreate for you. Try this:

Initial Configuration

init-author-name="Brooke Kuhlmann"
init-license="Hippocratic-2.1"
progress=false
save-prefix="~"

Steps

Notice I've made sure the registry is deleted this time. Now attempt to login via npm login. Here's what I see:

npm notice Log in on https://registry.npmjs.org/
Login at:
https://www.npmjs.com/login?next=/login/cli/<redacted>
Press ENTER to open in the browser...

So the above errors and I don't see //registry.npmjs.org/:_authToken=<redacted> written to my .npmrc file. However, if I click on the URL instead of hitting ENTER. This works!

By the way, in case this helps, I'm using my YubiKey to authenticate. Maybe there is some kind of delay the CLI fails to deal with that directly clicking the URL handles better?

manage to reproduce similer behaviour

1. Run npm login --no-progress
2. Hit Enter
3. It will open the browser but also it will error out in terminal

@bkuhlmann I see in your reproduction steps that you have one config progress=false. Could you please try without that config (i.e. something like npm login --progress=true) and see if that fixes your issue ?

[bkuhlmann]

Huh, sure enough, ensuring that --progress=true is used made this work! ...but if I disable progress then, yes, the login fails.
