Passing arguments into the resolvers by just using `buildSchema` and `graphql`? about graphql-js HOT 3 OPEN

The error message "Cannot read properties of undefined (reading 'name')" indicates that the name argument is undefined within your resolver.In this updated version, we are using destructuring to extract the name argument directly from the arguments object.Additionally, when constructing the GraphQL query in the source variable, we'll ensure that we're properly passing the name as a query parameter

if (req.method === 'GET' && (req.url === '/' || req.url.startsWith('/graphql'))) {

const urlParams = new URLSearchParams(req.url.split('?')[1]);
