ECONNREFUSED when running generate command

[theodesp]

Hello. I have a question that was initiated in old Faust.js project that may need you attention:

wpengine/faustjs#1216

Basically the user tries to run the generate command to create types for GQty but it fails with: ECONNREFUSED

@faustjs/[email protected] generate
gqty generate

Using "http://localhost:10004/graphql" to generate schema...
[Error: connect ECONNREFUSED ::1:10004] {
  errno: -61,
  code: 'ECONNREFUSED',
  syscall: 'connect',
  address: '::1',
  port: 10004
}

However the endpoint is enabled and can accept connections. Not sure why this is happening. Maybe you can shed some light.
