error in Suricata

Saw this error message in Suricata. Is this something I can just ignore or is this pointing to a problem? Currently have 8.8.8.8 and 8.8.4.4 as my primary dns entries in the firewall.

I'm seeing a similar issue. Is there is a fix/patch for this error?
I have IPS Mode and Promiscuous Mode enabled with Pattern Matcher = Hyperscan only on WAN Interface.

It is an error in the rules file. Has to be fixed by the provider of the rule set. Maybe the rules are not compatible with your suricata version.
