Unable to retrieve user profile photos using ProfilePhotosOf method

[nkbmdev]

I am trying to retrieve a user’s profile photo using the Telebot library, but the ProfilePhotosOf method always returns an empty array. I’ve tried different approaches, but the result remains the same:

1. WebApp InitData - returns empty photo_url.
2. ProfilePhotosOf method - always returns an empty array, regardless of the account. The user has set profile photo visibility to public, and their profile photo displays correctly in other bots.

Code Example:

const BotToken = "YOUR_TOKEN"
const UserID int64 = 0    // telegram users id

func Example_GetUsersProfilePhotos() {
    pref := telebot.Settings{
        Token:  BotToken,
        Poller: &telebot.LongPoller{Timeout: 10 * time.Second},
    }
    bot, err := telebot.NewBot(pref)
    if err != nil {
        fmt.Println(err)
    }

    user := telebot.User{ID: int64(UserID)}
    photos, err := bot.ProfilePhotosOf(&user)
    if err != nil {
        fmt.Println("Error retrieving photos")
        return
    }

    fmt.Println(photos) // always returns an empty array
}

Question:

Why does the ProfilePhotosOf method always return an empty array? Am I missing something in the settings or initialization? Any advice or ideas on how to solve this issue would be appreciated.
