Bug: ... ERROR /config/updates.json validation error: IP 2 of 2 is empty for record

[Narflar]

If a domain from the config never gets an IP, the updates.json stays empty (ip": "",), If I start ddns-updater it registers that empty IP as an error and shuts down. I have to delete the updates.json before I restart ddns-updater.

TLDR: blank IPs in updates.json crash the app.

1. Is this urgent: No
2. DNS provider(s) you use: Cloudflare / google
3. Program version: Running version latest built on 2021-12-04T21:55:55Z (commit fa15abb)
4. What are you using to run the container: docker, Synology
5. Extra information (optional)
