Telegram sendMediaGroup can not be used to send album of variable anount of pictures

[io_io]

It looks like there is no way to use Telegram sendMediaGroup node to send a bunch of pictures as an album. It works only if node gets static number of pictures.

Multiple images in telegram

I see, so you don’t have the actual files in n8n but instead have URLs you want to share in Telegram? And these URLs would come through as an array in a single attachments field for each of your items? My suggestion would be an approach like this: Convert each individual string in your attachments arrays into individual items.

Hey @io_io,

If looks like we only support sending a known amount of items at the moment. I have changed this to a feature request so we can think about adding this in the future.
