Error installing BigTree on MAMP

I am trying to install BigTree version 4.5.13 on MAMP version 5.0.6, which uses PHP version 8.3.1 and MySQL version 5.7.24. I get an error when installing, and get a HTTP 500 error. The install page displays correctly, but when clicking the BigTree install button, the page refreshes to a HTTP 500 error. The first 2 tables in the database are created, I'm not sure if they are successfully created, but they do exist. They are bigtree_404s and bigtree_audit_trail.

This is the logged error from php_error.log
[07-Aug-2025 09:15:35 Etc/GMT+6] PHP Fatal error:  Uncaught mysqli_sql_exception: Invalid default value for 'expires' in C:\MAMP\htdocs\btt\install.php:38
Stack trace:
#0 C:\MAMP\htdocs\btt\install.php(38): mysqli->query('CREATE TABLE `b...')
#1 C:\MAMP\htdocs\btt\install.php(250): sqlquery('CREATE TABLE `b...')
#2 {main}
  thrown in C:\MAMP\htdocs\btt\install.php on line 38

I tried installing the same version of BigTree on MAMP version 4.2.0, which uses PHP version 7.4.1 and MySQL version 5.7.24 and BigTree installed without issue.
