func (u *userRouter) create(c *gin.Context) { fmt.Println("create 입니다") var req types.CreateRequest if err := c.ShouldBindJSON(&req); err != nil { u.router.failedResponse(c, &types.CreateUserResponse{ ApiResponse: types.NewApiResponse(-1, "바인딩 오류", err), }) } else if err := u.userService.Create(req.ToUser()); err != nil { u.router.failedResponse(c, &types.CreateUserResponse{ ApiResponse: types.NewApiResponse(-1, "바인딩 오류", err), }) } else { u.router.okResponse(c, &types.CreateUserResponse{ ApiResponse: types.NewApiResponse(1, "성공 입니다.", err), }) }   package types type ApiResponse struct { Result int64 json:"result" Description string json:"description" ErrCode interface{} json:"errCode" } func NewApiResponse(Result int64, Description string, errCode interface{}) *ApiResponse { return &ApiResponse{ Result: Result, Description: Description, ErrCode: errCode, } }   package types type User struct { Name string json:"name" Age int64 json:"age" } type CreateUserResponse struct { *ApiResponse } type CreateRequest struct { Name string json:"name" binding:"require" Age int64 json:"age" binding:"require" } func (c CreateRequest) ToUser() User { return &User{ Name: c.Name, Age: c.Age, } } type GetUserResponse struct { *ApiResponse Users []*User json:result } type UpdateUserResponse struct { *ApiResponse } type UpdateRequest struct { Name string json:"name" binding:"require" UpdateAge int64 json:"updateAge" binding:"require" } type DeleteUserResponse struct { *ApiResponse } type DeleteRequest struct { Name string json:"name" binding:"require" } func (c DeleteRequest) ToUser() User { return &User{ Name: c.Name, } }   이렇게 되는데 if err := c.ShouldBindJSON(&req); err != nil {   여기서 문제가 발생했다고 합니다. 이유를 잘 모르겠습니다.

어떤 코드인지 샘플 올려주실 수 있을까요?   보시면 require문에서 발생을 하였고 벨리데이트할 때 발생을 한걸로 보이는데   어딘가에 오타나 타입선언하실 때 먼가 문제가 있어보입니다.   간단한 코드 보내주시면 감사하겠습니다.
