What happened: time="2024-09-22T14:36:23Z" level=info msg="add *.xxx.com IN A -> 192.168.1.220" time="2024-09-22T14:36:23Z" level=fatal msg="Failed to do run once: Domain '*.xxx.com' is not valid"

What you expected to happen:

Provide configuration option to exclude wildcard domains.

How to reproduce it (as minimally and precisely as possible):

I installed external-dns by Helm, configured with source ingress, when I try to create a ingress with TLS certificate domain name *.xxx.com and a certificate issuer with DNS-01 resolver, host is my-ingress.xxx.com, external-dns try to call Pihole API to create an A record for *.xxx.com, which throws the error and external-dns turn to CrashLoopBackOff

Anything else we need to know?:

Environment:

• External-DNS version (use 0.15.0):
• DNS provider: PiHole
• Others:
