you will get a text version, with:

Validation errors:

```

### Override the `HTTPException` error handler { #override-the-httpexception-error-handler }

The same way, you can override the `HTTPException` handler.

package config

// UI errors
var (
	ErrInvalidXLValue = newErrFn(
		"Invalid drive path",
		"Please provide a fresh drive for single drive MinIO setup",
		"MinIO only supports fresh drive paths",
	)

	ErrInvalidBrowserValue = newErrFn(

import (
	"fmt"
)

// ErrUnknownRegion - unknown region error.
type ErrUnknownRegion struct {
	Region string
}

func (err ErrUnknownRegion) Error() string {
	return fmt.Sprintf("unknown region '%v'", err.Region)
}

// ErrARNNotFound - ARN not found error.
type ErrARNNotFound struct {
	ARN ARN
}

func (err ErrARNNotFound) Error() string {
	return fmt.Sprintf("ARN '%v' not found", err.ARN)
}

        }
    ]
}
```

вы получите текстовую версию:

```
Validation errors:
Field: ('path', 'item_id'), Error: Input should be a valid integer, unable to parse string as an integer
```
