wrong reason:

 const {
        data: {
          status,
          msg
        },
        data: {
          users,
          total
        }
      } = res.data

Looking at the code carefully, I found that there are two objects in the const, both of which are data, and the data returned by the background should be a data and a meta.
I also tell my friends here that you must be careful when typing the code
