Bubblewrap error in using Composer

Hi, i want to use bubblewrap with “jailbash” in my HestiaCP server. After execute “v-add-user-composer example” and login to user - i can’t use composer because I have errors with PHP configuration:

PHP Warning: PHP Startup: Invalid date.timezone value ‘UTC’, using ‘UTC’ instead in Unknown on line 0
PHP’s phar extension is missing. Composer requires it to run. Enable the extension or recompile php without --disable-phar then try again.

But in my PHP configuration for CLI - I have set:

date.timezone = “Europe/Warsaw”

Any ideas to repair it?
