How should I configure exim4 in Debian 11 to send mail successfully?

Question

I tried to configure exim4 in debian 11 after referring to the following links:

https://alexander.holbreich.org/exim-mail-google/ and

https://bobcares.com/blog/exim4-smtp-authentication/

I tried sudo dpkg-reconfigure exim4-config but it fails with the following options

• Send mail as smarthost
• System mail name set as my hostname:tickets.informatics.org (only locally configured -not available on internet)
• IP-addresses to listen on for incoming SMTP connections as: 127.0.0.1 ; ::1 ; 192.168.2.160 where 192.168.2.160 is my local ip address
• Other destinations for which mail is accepted: set empty
• Machines to relay mail for: localhost; 192.168.2.0/24
• IP address or host name of the outgoing smarthost: smtp.gmail.com::587
• Hide local mail name in outgoing mail? - Yes
• Visible domain name for local users: tickets.informatics.org
• Keep number of DNS-queries minimal (Dial-on-Demand)? No
• Keep number of DNS-queries minimal (Dial-on-Demand)? mbox format in /var/mail/
• Split configuration into small files? No

After completing configuration I get the error message:

2022-07-18 14:50:06 Exim configuration error in line 933 of /var/lib/exim4/config.autogenerated.tmp:
  authenticator name missing
Invalid new configfile /var/lib/exim4/config.autogenerated.tmp, not installing 
/var/lib/exim4/config.autogenerated.tmp to /var/lib/exim4/config.autogenerated

I also followed the second link and did changes as mentioned in the link. When I run sudo systemctl status exim4 I get the failed status message:

How can I fix the error to send email using exim mail server and mail or sendmail command from my Debian 11 system. Please help
