Undefined array key "type"

[samdark]

I'm getting Undefined array key "type" error from time to time at production:

    private function validateMxRecord($dnsRecord) : bool
    {
        if ($dnsRecord['type'] !== 'MX') {
            return true;
        }

Relevant trace:

Email validated is [email protected]. It looks like dns_get_record might return info element w/o type specified.

Same issue with more emails such as [email protected].

PHP version is 8.1.6 OS is latest Alpine in Docker.

Thanks @samdark! dns_get_record is tricky to test. Happy to review and merge a PR ;)

Hi @samdark , should be fixed in v3.2 now. Please let me know

I'll try upgrading and deploying it to production soon.

Seems the problem is gone. Thank you.
