invalid_ip_allow_list

HTTP 422. An entry in ip_allow_list is not a valid IP address or CIDR range, so the key was not created.

What to do: Read detail; it names the entry that failed. Each one must be an IP (203.0.113.7) or a CIDR range (203.0.113.0/24).

Every error is an RFC 9457 problem document - match on code (stable forever), show detail to humans, and quote instance when reporting an occurrence to support.
