These records are logged when your Squid is done with an HTTP CONNECT
tunnel or after Squid intercepts a TLS connection. In very broad terms,
they are a sign that your Squid participates in HTTPS transactions.
Normally, there should be more than "https:443" in those CONNECT records.

Consider either fixing the scripts or, if losing information about
CONNECT tunnels is acceptable to your accounting, filtering CONNECT
records out before giving the logs to the scripts.

You can also configure Squid to stop logging CONNECT transactions (using
access_log ACLs), but I do not recommend hiding the truth that may be
critical in a triage.
