Cannot read property 'indexOf' of undefined

With following script defined in package.json:

"lint:outdated": "assert-outdated-npm-modules --max-warnings 0 --ignore-pre-releases",

1. Ran lint:outdated and got a list of outdated dependencies (as expected)
2. Updated package.json with new versions
3. Ran lint:outdated again, and got following errror (not expected):

C:\dev\project>npm run lint:outdated

> project@0.1.0 lint:outdated C:\dev\project
> assert-outdated-npm-modules --max-warnings 0 --ignore-pre-releases

TypeError: Cannot read property 'indexOf' of undefined
    at C:\dev\project\node_modules\assert-outdated\outdated.js:23:26

    at C:\dev\project\node_modules\assert-outdated\outdated.js:62:27

5. Ran npm install to see if that helped
6. Ran lint:outdated once again, and got no errors (as expected)

Seems when I update package.json, but don't run npm install, then outdated.js crashes for some reason?

Thank you for using this module! Great that you found an error and reported it.

This error should of course not happen.
Do you feel comfortable writing a pull request with a test? I would publish a fixed version ASAP.

Best!

@mren Definitely not, as I don't really understand what's happening in the first place. 😛 I did take a look at the code, but yeah, very newb in the non-browser javascript world... 😕

Hey, no Problem! I currently don’t have the capacity to do this. If you feel like you are up to a challenge feel free to have a look. I can assist you with any questions you might have. Best!

@Svish Can you provide the package.json? And which version of npm (npm -v) and node.js (node -v) are you using? I'll take a look into this.

Long gone I'm afraid. But should be possible to replicate easily by making a simple one with just one outdated dependency and this one?
