Hi @nic11371 ,

which n8 version do you use?

I just tested it with n8n version 1.112.5 and it works fine!
Caption is only shown for the last file.

Yes, I’ve actually faced this issue before and I think I know the reason behind it.

The problem occurs when you upload multiple images along with a caption, Telegram assigns the caption to only one of the images, while the rest remain without a caption. That’s why in n8n you “sometimes” get a caption and “sometimes” you don’t, it’s random at this point!

I’m not sure if this is something that can be fixed on the n8n side, or if it’s a limitation from Telegram itself.

I use 1.106.3. I updated the version n8n to 1.112.5. The problem remains.

[nic11371]

Thank you. It seems to me that the problem is that node telegram in n8n. It is a bag. It should be correct..

Ah, I allways tried with one image!
Now I tested with 2 images an can confirm this issue!
No caption is received…
