Minify in general settings is enabled and on manual.
Minify for CSS / JS is enabled at the minify settings.
But nothing happens.

As soon as I change to AUTO, it works.

Environment:
Docker containers:

• wordpress:5.4-php7.4
• mysql:5.7
• redis

I have confirmed that Redis is working and is connected through the Redis Object Cache plugin. I had to modify the wp-config.php to include the Redis configuration information. I also added in the db-config.php file within the W3 cache plugin directory with the following settings:

//
// redis config cache
//
define( 'W3TC_CONFIG_CACHE_ENGINE', 'redis');
define( 'W3TC_CONFIG_CACHE_REDIS_SERVERS', 'site1-cache::6379' );

// optional redis settings
define( 'W3TC_CONFIG_CACHE_REDIS_PERSISTENT', true );
define( 'W3TC_CONFIG_CACHE_REDIS_DBID', 0 );
define( 'W3TC_CONFIG_CACHE_REDIS_PASSWORD', '' );

wp-config.php (redis section)

/** Define Redis Caching **/
define('WP_REDIS_HOST', 'site1-cache');
//define('WP_REDIS_CLIENT', 'predis'); // appears that even though PHPredis is specified below, the plugin still utilizes predis
define('WP_REDIS_CLIENT', 'phpredis');
//define('WP_CACHE', 'true'); // this is already defined at the top of the file.
define('WP_CACHE_KEY_SALT', 'site1');
define('WP_REDIS_DISABLE_BANNERS', 'true');
define('WP_REDIS_DATABASE', '0');
define('WP_REDIS_TIMEOUT', '5'); // timeout in seconds
define('WP_REDIS_READ_TIMEOUT', '5'); // Read timeout in seconds
define('WP_REDIS_RETRY_INTERVAL', '100'); // Retry interval in milliseconds

Is there something that I’m doing wrong in order for W3 to actually recognize Redis as an option for caching?

I want basically an automatically way to delete all minify caches as soon as I make any changes within js files.
