Question

I use telegraf and when send photo by url become such problem but when I use local photo(../img.jpg) it is okey. Code:

 bot.hears(/\/pic/, ctx=> { let photo = 'https://img-9gag-fun.9cache.com/photo/azmpDRN_460s.jpg'; bot.telegram.sendPhoto(chatId, {source: photo}, {caption: "Hello"}); });

Answer 1

I need to change 'source' to 'url':

 bot.hears(/\/pic/, ctx=> { let photo = 'https://img-9gag-fun.9cache.com/photo/azmpDRN_460s.jpg'; bot.telegram.sendPhoto(chatId, {url: photo}, {caption: "Hello"}); });
