[]*time.Time | panic: value method time.Time.MarshalJSON called using nil *Time pointer #523
Description
Example code with panic in go-json, but in encoding/json all good:
package main
import (
"encoding/json"
"fmt"
"time"
gojson "github.com/goccy/go-json"
)
func main() {
data := []*time.Time{nil}
b, _ := json.Marshal(data)
fmt.Printf("std: %s\n", string(b))
b, _ = gojson.Marshal(data)
fmt.Printf("go-json: %s\n", string(b))
}Output:
std: [null]
