webdriver-manager update with --alternate_cdn argument - protractor

Question

I want to do the below in my protractor-cucumber framework. I can not use public repo like googleapi.com as per org policy:
webdriver-manager update --standalone=0 --chrome --alternate_cdn https://www.artifactrepository.xyz.net/artifactory/api/npm-teamdev/
Also this:
webdriver-manager update --chrome=0 --standalone --alternate_cdn https://www.artifactrepository.xyz.net/artifactory/api/npm-teamdev/
But i always get this as response:
C:\Users\ABCD\Desktop\JSProjects\protractor-cucumber>webdriver-manager
update --standalone=0 --chrome --alternate_cdn
https://www.artifactrepository.xyz.net/artifactory/api/npm/npm-teamdev/
curl -o

I have also tried to modify the cdn url in ./node_modules/protractor/node_modules/webdriver-manager/config.json
{
"cdnUrls": {
"selenium": "https://www.artifactrepository.xyz.net/artifactory/api/npm/npm-teamdev/",
"chromedriver": "https://www.artifactrepository.xyz.net/artifactory/api/npm/npm-teamdev/",
"geckodriver": "https://www.artifactrepository.xyz.net/artifactory/api/npm/npm-teamdev/",
"iedriver": "https://www.artifactrepository.xyz.net/artifactory/api/npm/npm-teamdev/"
}
}
This one also did not work for me. I got the same error.
I want to know what's the issue here and how can how to resolve it?
Does webdriver-manager expect xml when the request hits custom CDN url?
If yes, is there a way to update if it returns html instead of xml. Because I can see all these drivers in the repo.
