It seems like $title defined by $semanticData->getSubject()->getTitle() on line 54 can be null; however, SESP\AppFactory::newUserFromTitle() does not accept null, maybe add an additional type check?

		$dataItem = null;

		if ( $user instanceof User ) {

The class User does not exist. Is this class maybe located in a folder that is not analyzed, or in a newer version of your dependencies than listed in your composer.lock/composer.json?

			$timestamp = wfTimestamp( TS_ISO_8601, $user->getRegistration() );
			$date = new \DateTime( $timestamp );

			$dataItem = new DITime(
				DITime::CM_GREGORIAN,
				$date->format('Y'),
				$date->format('m'),
				$date->format('d'),
				$date->format('H'),
				$date->format('i')
			);
		}

		if ( $dataItem instanceof DataItem ) {
			$semanticData->addPropertyObjectValue( $property, $dataItem );
		}
	}
