Just reporting here as suggested.
WARNING: /core/CliMulti/Process.php(259): Deprecated - trim(): Passing null to parameter #1 ($string) of type string is deprecated - Matomo 4.12.3 - Please report this message in the Matomo forums: https://forum.matomo.org (please do a search first as it might have been reported already) (Module: Installation, Action: getSystemCheck, In CLI mode: false)
#### PHP version >= 7.2.5: ✔ 8.1.12
Matomo Version 4.12.3
Would be great to get Mamoto fixed for current stable PHP.
