Golang request body keep giving EOF error

I have the following Go program which I want to read the JSON values send from via post. I have tried few different methods example r.Body = http.MaxBytesReader(w, r.Body, 1048576) first then only run Json.NewDecoder(r.Body).Decode(&u). All methods seems to be giving the same EOF error. I have even tried this body, err := ioutil.ReadAll(r.Body). So all seem the same

func insertUser(w http.ResponseWriter, r *http.Request) {
  type User struct {        
    Uemail string `json:"uEmail"`
    Upass string `json:"uPass"`    
  }
  var u User
  if r.Method == "POST" {
    if r.Header.Get("Content-Type") != "" {
      value, _ := header.ParseValueAndParams(r.Header, "Content-Type")
      if value != "application/json" {
          msg := "Content-Type header is not application/json"
          json.NewEncoder(w).Encode(Errormessage{msg});
          return
      }
    }
    //r.Body = http.MaxBytesReader(w, r.Body, 1048576)
    /*body, err := ioutil.ReadAll(r.Body)
    if err != nil {
        return err
    }*/
    err := json.NewDecoder(r.Body).Decode(&u)
    if err != nil {
      fmt.Println("Decoding error is :", err)
      json.NewEncoder(w).Encode(Errormessage{"Message decoding Issue"});
        return
    }
    var uEmail string = u.Uemail
    var uPass string = u.Upass
   
    fmt.Println("User Namess :", uEmail)
    fmt.Println("User Password :", uPass)

    w.Header().Set("Content-Type", "application/json; charset=utf-8")
    w.Header().Set("X-Content-Type-Options", "nosniff")
  }

Please try running the following

func insertUser(w http.ResponseWriter, r *http.Request) {
  type User struct {        
    Uemail string `json:"uEmail"`
    Upass string `json:"uPass"`    
  }
  var u User
  if r.Method == "POST" {
    if r.Header.Get("Content-Type") != "" {
      value, _ := header.ParseValueAndParams(r.Header, "Content-Type")
      if value != "application/json" {
          msg := "Content-Type header is not application/json"
          json.NewEncoder(w).Encode(Errormessage{msg});
          return
      }
    }

    // CODE CHANGED HERE
    body, err := ioutil.ReadAll(r.Body)
    defer r.Body.Close()
    if err != nil {
        // handle error
        return
    }

    err = json.Unmarshal(body, &u)
    if err != nil {
        // handle error
        return
    }
    // CHANGED TILL HERE

    var uEmail string = u.Uemail
    var uPass string = u.Upass
   
    fmt.Println("User Namess :", uEmail)
    fmt.Println("User Password :", uPass)

    w.Header().Set("Content-Type", "application/json; charset=utf-8")
    w.Header().Set("X-Content-Type-Options", "nosniff")
  }
}
