ReadEnvInt returns int , here you don't need to use int()
| var pids, quantities []int | ||
| var products []Product | ||

| err = s.db.Select(&pids, getCartQuery, user_id) |

- handle err != nil , log error & return
- Why are you using two query to get data from two tables? add a single query to fetch data from cart

| query, args, err := sqlx.In(getProductsQuery, pids) | ||
| query = s.db.Rebind(query) |

here don't use sqlx.In with rebind .You can use exec() to fire any query
| for index, product := range products { | ||
| var category, image_urls []string | ||
| err = s.db.Select(&category, getCategoryQuery, product.CategoryId) | ||
| err = s.db.Select(&image_urls, getProductImageQuery, product.Id) |

use join to get details from other table
| logger.WithField("err", err.Error()).Error("Error listing cart") | ||
| return | ||
| } | ||
| fmt.Println(category, image_urls, index) |
| // @Failure 400 {object} | ||
| func getCartHandler(deps Dependencies) http.HandlerFunc { | ||
| return http.HandlerFunc(func(rw http.ResponseWriter, req *http.Request) { | ||
| // request_params := mux.Vars(req) |
| func listUsersHandler(deps Dependencies) http.HandlerFunc { | ||
| return http.HandlerFunc(func(rw http.ResponseWriter, req *http.Request) { | ||
| users, err := deps.Store.ListUsers(req.Context()) | ||
| fmt.Println(users) |

you are fetching category id for every record, you can join multiple tables using diff where clauses
| return | ||
| } | ||

| err = s.db.Select(&image_urls, getProductImageQuery, row.ProductId) |
