No message received by node-red-contrib-telegrambot if message contains a large video

holnburger commented 3 years ago

If I forward messages to the bot it works most of the time (Telegram Receiver + Debug Node) but if I'm forwarding a message with a large video file there's often no debug message trickered and it looks like the bot doesnt receive a message at all.

Example message: Forward with video doesn't work (isn't triggering the flow): https://t.me/auf1tv/227 Forward with video does work (is triggering the flow): https://t.me/auf1tv/259

Please send me a flow so that I can reproduce it

Sure.

Node-Red-Contrib-Telegrambot Version: 10.0.4 Node-Red Version Version 1.2.7

Possible source of problem: AutodownloadSetting is set to default value for the bot and media isn't downloaded because it's too big. See https://core.telegram.org/constructor/autoDownloadSettings

windkh commented 3 years ago

This seems to be a common problem: bots can only download up to 20MB. This limit is by design of the Telegram server API

see https://github.com/yagop/node-telegram-bot-api/issues/697
