Custom time.Time type is not receiving the complete date in UnmarshalJSON method.

Custom time.Time type is not receiving the complete date in UnmarshalJSON method.

Example Struct using the custom type JsonDate

type BeneficiaryTrust struct {
	tableName       struct{} `pg:"beneficiaries_trust"`
	ID              int64
	CreatedAt       time.Time   `json:"createdAt"`
	UpdatedAt       time.Time   `json:"updatedAt"`
	Name            string      `json:"name"`
	Established     db.JsonDate `json:"established"`
}

type JsonDate time.Time

func (j *JsonDate) UnmarshalJSON(b []byte) error {
	logger.GetLogger().Infof("%v",string(b))
	s := strings.Trim(string(b), "\"")
	t, err := time.Parse("2006-01-02", s)
	if err!=nil {
		return err
	}
	*j = JsonDate(t)
	return nil
}

func (j JsonDate) MarshalJSON() ([]byte, error) {
	return json.Marshal(time.Time(j))
}

Following go-pg method is failing with below error

var tBenes []models.BeneficiaryTrust
_, err = DB.Query(&tBenes, "select * from table")

ERROR:

parsing time \"2021\" as \"2006-01-02\": cannot parse \"\" as \"-\"",

Expected Behavior

All the database records from the table need to unmarshall properly into tBenes struct variable.

Current Behavior

Receiving the below error

parsing time \"2021\" as \"2006-01-02\": cannot parse \"\" as \"-\"",

It looks like you are logging the value of the byte array passed to UnmarshalJSON, what is that log entry say the value is?

Could you also include a stack trace of what code path in go-pg is calling UnmarshalJSON with this bad value?
