func (s *sftpLogger) Info(tag xsftp.LogType, msg string) {

...without adding the required parameter `needy`, you will see an error like:

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null,
      "url": "https://errors.pydantic.dev/2.1/v/missing"
    }
  ]
}
```

As `needy` is a required parameter, you would need to set it in the URL:

```

```JSON
{
  "detail": [
    {
      "type": "int_parsing",
      "loc": [
        "path",
        "item_id"
      ],
      "msg": "Input should be a valid integer, unable to parse string as an integer",
      "input": "foo",
      "url": "https://errors.pydantic.dev/2.1/v/int_parsing"
    }
  ]
}
```

	ErrConfigGeneric | ErrConfigNotFound
}

// ErrConfigGeneric is a generic config type
type ErrConfigGeneric struct {
	msg string
}

func (ge *ErrConfigGeneric) setMsg(msg string) {
	ge.msg = msg
}

func (ge ErrConfigGeneric) Error() string {
	return ge.msg
}

// ErrConfigNotFound is an error to indicate
// that a config parameter is not found
type ErrConfigNotFound struct {
	ErrConfigGeneric

)

//go:generate msgp -file $GOFILE -unexported

// healingTracker is used to persist healing information during a heal.
type healingTracker struct {
	disk StorageAPI    `msg:"-"`
	mu   *sync.RWMutex `msg:"-"`

	ID         string
	PoolIndex  int
	SetIndex   int
	DiskIndex  int
	Path       string
	Endpoint   string
	Started    time.Time
	LastUpdate time.Time

	ObjectsTotalCount uint64

	s.Split(loopAtEOFSplit)
	// Expect a panic
	defer func() {
		err := recover()
		if err == nil {
			t.Fatal("should have panicked")
		}
		if msg, ok := err.(string); !ok || !strings.Contains(msg, "empty tokens") {
			panic(err)
		}
	}()
	for count := 0; s.Scan(); count++ {
		if count > 1000 {
			t.Fatal("looping")
		}
	}
	if s.Err() != nil {

	"istio.io/istio/pkg/url"
)

...sans ajouter le paramètre requis `needy`, vous aurez une erreur :

```JSON
{
    "detail": [
        {
            "loc": [
                "query",
                "needy"
            ],
            "msg": "field required",
            "type": "value_error.missing"
        }
    ]
}
```

La présence de `needy` étant nécessaire, vous auriez besoin de l'insérer dans l'URL :

```

	Versioning *versioning.Versioning `msg:"-"`

	// Lifecycle performs filtering based on lifecycle.
	// This will filter out objects if the most recent version should be deleted by lifecycle.
	// Is not transferred across request calls.
	Lifecycle *lifecycle.Lifecycle `msg:"-"`

	// Retention configuration, needed to be passed along with lifecycle if set.
	Retention lock.Retention `msg:"-"`

	// Replication configuration

```

...필수 매개변수 `needy`를 넣지 않았기 때문에 아래와 같은 오류를 보게 됩니다:

```JSON
{
    "detail": [
        {
            "loc": [
                "query",
                "needy"
            ],
            "msg": "field required",
            "type": "value_error.missing"
        }
    ]
}
```

`needy`는 필수 매개변수이므로 URL에 반드시 설정해줘야 합니다:

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```
