[bug] ix map reports "Fetch failed" on node v18

[pboyd]

Description

I was running an older and apparently unsupported version of node and found that ix map failed with no indication of the problem. It worked fine after switching to a newer version.

I didn't see a minimum node version listed anywhere. I totally get why you wouldn't want to support older versions of node, but "Fetch failed" is hard to reason about.

Steps to reproduce

1. Run ix map . using an older version of node (I used v18.20.7, but I didn't check any others)

Expected behavior

I expected it to work, but an actionable error message would have been enough.

Actual behavior

A mysterious "Fetch failed" message.

CLI output

$ ix map .
[ok] Backend is already running and healthy
  Memory Layer: http://localhost:8090
  ArangoDB:     http://localhost:8529
  Ingested in 90.0s
Error: fetch failed

Environment

• OS: Linux
• Node: v18.20.7
• Ix version: 0.5.1
