Warning: getenv() expects exactly 1 parameter, 2 given in woocommerce error

I am getting a warning on my site but the line 55 in woocommerce-services.php

// Check for CI environment variable to trigger test mode.
	if ( false !== getenv( 'WOOCOMMERCE_SERVICES_CI_TEST_MODE', true ) ) {
		if ( ! defined( 'WOOCOMMERCE_SERVICES_LOCAL_TEST_MODE' ) ) {
			define( 'WOOCOMMERCE_SERVICES_LOCAL_TEST_MODE', true );
		}
		if ( ! defined( 'JETPACK_DEV_DEBUG' ) ) {
			define( 'JETPACK_DEV_DEBUG', true );
		}
	}

Unsure how to safely fix this. Any help would be appreciated. Thank you
