golang runtime error when i am trying to use db.QueryRow

i have controller.go:

package controller
import (
    "github.com/fishkaoff/todoList/pkg/postgresql"
    "github.com/gin-gonic/gin"
    "net/http"
    "context"
)

type Task struct {
    Title string 
    Description string
 }


func GetTasks(c *gin.Context) {
    var response *Task
    err := db.Conn.QueryRow(context.Background(), "select * from tasks").Scan(&response.Title, 
    &response.Description)
    if err != nil {
	    c.JSON(http.StatusInternalServerError, gin.H{"error":"error"})
    }

    c.JSON(200, gin.H{
	    "page":"gettasks",
	    "tasks": response,
    })
}

when i am sending request it returns me

db.Conn is imported from db.go:

    package db


    import (
	    "os"
	    "fmt"
	    "context"


	    "github.com/jackc/pgx/v4/"
	    "github.com/fishkaoff/todoList/internal/config"
    )

    var Conn *pgx.Conn

    func InitDatabase(config config.Config) {
	    Conn, err := pgx.Connect(context.Background(), config.DBUrl)
	    if err != nil {
		    fmt.Fprintf(os.Stderr, "Unable to connect to database: %v\n", err)
		    os.Exit(1)
	    }
	    defer Conn.Close()
    }

InitDatabase is calling in main.go

in database table and columns are created

i am using pgx v4

P.S: sorry for my bad english, i am not a native speaker

    var response *Task

You have allocated memory to store a *Task, not a Task.

Then when you

    .Scan(&response.Title,     &response.Description)

Attempt to take the address of response.Title and response.Description. These fields don't have an address because response is a pointer but doesn't point to a valid task.

Try:

var response Task

Now you actually have allocated space for the Title and Description fields and thus have somewhere to store those values.
