Describe the problem/error/question

Hi everyone,

I’m trying to send a PDF document from n8n to Telegram, but I keep getting the following error:

ERROR: Storage mode used to store binary data not available

Simple message to telegram chat works as expected.

Hey @vladpavlovski,

What version of n8n are you running and does it work if you set the binary data mode to default?

[vladpavlovski]

I’m using n8n Version: 0.222.1.

I solved it by removing middle Code step and sending pdf file from first IMAP Email step.
