you have proxy settings that point to a proxy called `proxy-server` but within your network, that name entry does not resolve into actual ip address. Eg, you see the error:

code: ‘EAI_AGAIN’,
syscall: ‘getaddrinfo’,
hostname: ‘proxy-server’

Probably issue within your .npmrc file or environment variables that tries to configure proxy but hard to say because those details are not shared.
