Why doesn’t 'dive' work on gin? (about validator)

Question

I just would like to do like the below about validation on Gin(Golang).

type Accounts struct {
    Accounts []*Account `json:"accounts" binding:"required,dive"`
}

type Account struct {
    BusinessId string `json:"business_id" binding:"required,min=1,max=50"`
    Token  string `json:"token" binding:"required,min=1,max=100"`
    UserId     string `json:"user_id" binding:"required,min=1,max=50"`
}

import (
    "reflect"

    "github.com/gin-gonic/gin"
    "github.com/gin-gonic/gin/binding"

    "github.com/go-playground/validator/v10"
)

func Validator(c *gin.Context, request interface{}) (interface{}, []string) {
    var err []string

    errors := c.ShouldBind(&request)

    if errors != nil {
        var messages []string
        for _, m := range errors.(validator.ValidationErrors).Translate(t) {

            messages = append(messages, m)

        }

        err = messages

    }

    return request, err
}

_, errors := pkg.Validator(c, Accounts{})

    if errors != nil {

        exceptions.Validation(errors, c)
        return
    }

Why doesn’t work? Please teach me how works.

I would like to validate array on Gin(Golang). I tried to use 'dive', but it looks like not working.
