Running Cron with PHP on macOS 12 Throws Error - Could not open input file

I have this in my crontab:

* * * * * /Applications/MAMP/bin/php/php7.2.10/bin/php -f /Users/user/Documents/radio_bycron.php 2>&1 > /Users/user/Documents/radio_bycron.php_output.txt

In /Users/user/Documents/radio_bycron.php_output.txt, there's only one line which is:

Could not open input file: /Users/user/Documents/radio_bycron.php

I have already chmod 0777 the script /Users/user/Documents/radio_bycron.php, but I am still getting this issue. The problem happens with or without the -f flag. If I execute the command directly on the Terminal, it works perfectly. How can I solve this problem?
