export XDEBUG_SESSION="PHPSTORM" doesn't initiate listening in PhpStorm

[gitressa]

• Ubuntu 20.04
• Lando v3.14.0
• Drupal 10

Using Lando + PhpStorm + Xdebug, Manual initiation with https://drupal10.lndo.site?XDEBUG_SESSION_START=lando works well, and PhpStorm grabs focus, showing me the variables at the break point.

But I am also trying to initiate PhpStorm and Xdebug from the CLI, but can't make this method work:

export XDEBUG_SESSION="PHPSTORM"

I added this in index.php and verified that xdebug.trigger_value isn't set:

xdebug_info();
exit;

The value of the variable does not matter unless you have set up a trigger value with xdebug.trigger_value.
