[BUG] "npm ERR! cb() never called" Error thrown in case of a proxy authentication error

[andy-schulz]

What / Why

I am behind an authenticated corporate proxy.

To set the proxy i am using

npm config set proxy http://username:password@proxy.company.com
npm config set https-proxy http://username:password@proxy.company.com

I had to reset the passord but forgot to reset it for npm.

When running:

npm install

npm responded with the error

 error cb() never called!

Changing the password with npm config set proxy fixed the problem.

Where

• Windows 10 VM
• npm@6.13.1
• node@v10.15.3

Current Behavior

npm install throws error cb() never called!

Expected Behavior

I would like to see a 407 Proxy Authentication Error printed to console and not just to the log.
