Debugging is not working in VS code. after upgrading php version from 7.2 to 7.4

Question

I have upgraded my PHP version from 7.2 to 7.4 and I found that debugging has stopped in all projects.

My configurations are-

zend_extension="/usr/lib/php/20190902/xdebug.so"
xdebug.remote_autostart = 1
xdebug.remote_enable = 1
xdebug.remote_handler = dbgp
xdebug.remote_host = 127.0.0.1
xdebug.remote_log = /tmp/xdebug_remote.log
xdebug.remote_mode = req
xdebug.remote_port = 9000

I have added the above configuration in the following files-

• /etc/php/7.4/apache2/php.ini
• /etc/php/7.4/apache2/conf.d/20-xdebug.ni
• /etc/php/7.4/cli/conf.d/20-xdebug.ni
• /etc/php/7.4/mods-available/xdebug.ini

php -v command is returning the following output-

I have installed the Xdebug extension in VS code too-

phpinfo(); function is returning the following output-

How should I do to resolve my issue?

If you use Xdebug with version 3 , you have to config again parameters. ( https://xdebug.org/docs/upgrade_guide#Step-Debugging ). Based on the shared documentation, I will suggest the following config:

zend_extension = "/usr/lib/php/20190902/xdebug.so"
xdebug.start_with_request = yes
xdebug.mode = debug
xdebug.client_host = 127.0.0.1
xdebug.log = /tmp/xdebug_remote.log
xdebug.client_port = 9000
xdebug.idekey = VSCODE
