Telegram bot api: sendPhoto do not render html

Question

I'm composing messages in this way

const reply_telegram = {
        "chat_id"               : MIRKO,
        "photo"                 : row.image_url,
        "caption"               : '<b>Wow</b>',
        "parse_mode"            : "HTML",
        "disable_notification"  : true,
}

For the goal of this question, focalize on

"parse_mode" : "HTML"

I am usng the sendPhoto instead of classic sendMessage.

Official docs state that I can use a caption and parse_mode in the sendPhoto method

I am actively using sendMessage with html content, and it's handled as HTML as I want

In short, the problem is that: message is sent, photo is delivered, caption text is printed under the photo, tags are not printed, but the title is not bold as I requested.

What am I missing?

If this.title is 'wow', I send the caption param as `wow`. The bot accepts it, but it simply write `wow` — realtebo, Jul 31 '18 at 05:31
After `"caption" : 'Wow'` you have omitted the comma. can you verify that this is not the problem? — Antonio Altieri, Sep 21 '18 at 10:45
@AntonioAltieri: thanks, but it was just an error when copying code into this question. In the code the command is present. I upvote your comment and modify the question, because the problem is still present — realtebo, Sep 22 '18 at 20:16
Try using &lt instead of < and &gt instead of > in the html tag. — Ricardo Ortega Magaña, Sep 22 '18 at 20:23
@RicardoOrtegaMagaña: thanks but using entities instead of literals do not works, the < and the > are litterally rendered. I must simply wait for telegram to fix rendering probably. — realtebo, Sep 22 '18 at 20:29
Is working like its supposed, you have some mispell maybe? look at this link, just change your Token and chatid: https://api.telegram.org/bot/sendPhoto?chat_id=&photo=https://ih0.redbubble.net/image.479168030.1016/flat,550x550,075,f.u2.jpg&caption="Hola"&parse_mode=HTML — Ricardo Ortega Magaña, Sep 22 '18 at 20:34
@RicardoOrtegaMagaña: now it works, after some updates from Twitter — realtebo, Jan 25 '19 at 08:26

Actually, July of 2019, seems that the problem is no more present. Probably Twitter has fixed it.
