PHP Fatal error: Uncaught Error: Call to a member function convert() on null in /var/www/MintHCM/legacy/modules/OAuth2Tokens/OAuth2Tokens.php:134
after some digging around if found out this error occurs because the $db is null indicating the database is not connected.
I mentioned there is a html page in the install log, indeed asking for a database name.
I have a DB_NAME in my .env file and the content of that var also ends up in configMint4 file. I wonder why this is not used by the installer
