How to use execute javascript using webautomation package

in A360

Any function? Can someone demonstrate how I can get the following simple RexExp function to work without returning “bot error”. It should return:

“PCAGoldenValleyMinneapolisOpportunities_ST20240501-ED20241101_20240820-0855-PACOA-FRV.xls,PCAGoldenValleyMinneapolisOpportunities,20240501,20241101,20240820-0855-PACOA-FRV,20240820-0855,PACOA”

function string_parse(source, regex) { return source.match(new RegExp(regex)).toString(); }

results = string_parse(    'PCAGoldenValleyMinneapolisOpportunities_ST20240501-ED20241101_20240820-0855-PACOA-FRV.xls',    '^([A-Za-z0-9\\-]+)_ST(\\d{8})-ED(\\d{8})_((\\d{8}-\\d{4})-([A-Za-z0-9]+)-[A-Za-z0-9]+)\\.xls'    //'^(?<Description>[A-Za-z0-9\\-]+)_ST(?<StartDate>\\d{8})-ED(?<EndDate>\\d{8})_(?<BidId>(?<BidDateTime>\\d{8}-\\d{4})-(?<BidCustomerCode>[A-Za-z0-9]+)-[A-Za-z0-9]+)\\.xls');

console.log(results);
