@xf039 why'd you close this?

@LukeTowers my default OS PHP version is php 5.4. I ran composer as php72, some automated commands fall back to using php what resulted in artisan october:util set build being executed as php 5.4 instead of 7.2.

I contacted with hosting administrator and they are updated Php version to 7.3 but problem not solved currently 😒

@Developer-Nijat sounds like your webserver isn't properly using the correct PHP version, double check with your hosting administrator to verify that your server software is actually running PHP 7.2 at a minimum.

Sure. Problem solved after upgrading php version to 7.3 for specific subdomain and main domain.
