Undefined array key in class-fremius.php:4232

Reported by @MacGyer in TablePress/TablePress#199:

When CLI scripts run, an error is thrown:

PHP Warning: Undefined array key "HTTP_HOST" in /path/to/tablepress/libraries/freemius/includes/class-freemius.php on line 4232

• WP: 6.6.x

Error has moved, but is still present.

My customers have also reported this issue. They encountered the error while running a cron job. The PHP CLI does not have access to $_SERVER['HTTP_HOST'].

We solved this problem, by adding the --url flag to our wp cli command.
Doc: https://make.wordpress.org/cli/handbook/references/config/

Example:
wp cron event run --due-now --url=https://www.your-http-host.com

the --url parameter calls the WP_CLI::set_url() function and sets $_SERVER['HTTP-HOST']

or skip the plugin via wp_cli --skip-plugins parameter
Example:
wp cron event run --due-now --skip-plugins=your-plugin-with-http_host-error

Maybe it helps
