unique validator for map with Pointer value is not properly validated

[vijaynallagatla]

• I have looked at the documentation here first?
• I have looked at the examples provided that may showcase my question here?

Package version eg. v9, v10:

v10

Issue, Question or Enhancement:

Issue: Validator tag unique on kind Map with pointer value doesn't seem to be evaluating properly.

Code sample, to showcase or reproduce:

package main

import (
	"fmt"
	"github.com/go-playground/validator/v10"
)

type Class struct {
	Sub map[string]*string `validate:"unique"`
}

var validate *validator.Validate

func main() {
	validate = validator.New()
	validateStruct()
}

func validateStruct() {
	data := Class{
		Sub: map[string]*string{
			"one": strPtr("abc"),
			"two": strPtr("abc"),
		},
	}

	nonPointer := struct {
		Sub map[string]string `validate:"unique"`
	}{
		Sub: map[string]string{
			"one": "abc",
			"two": "abc",
		},
	}

	err := validate.Struct(data)
	if err != nil {
		fmt.Println("Error with pointer validation %w", err)
	}

	err = validate.Struct(nonPointer)
	if err != nil {
		fmt.Println("Error with struct validation %w", err)
	}

}

func strPtr(a string) *string {
	return &a
}
