get http-functions

The results that are returned are rows, so you can get all of the fields that you want from the returned results. I’ve added a couple of lines to your code to illustrate:

export function get_myFunction(request) {
   return wixData.query("myUsersCollection")
      .eq("firstName", request.path[0])
      .find()
      .then((results) => {
         if (results.items.length > 0) {
            const body = "Found it!";
            let item = results.items[0]; // get first row of results
            let lastName = item.lastName;// get desired field
            return ok({ body: body });
         }
         const body = "Not in the system";
         return notFound({ body: body });
      });
}

I hope this helps.
