ID gmail items with attachment?

Describe the problem/error/question

What is the error message (if any)? if node always evaluates to false regardless of the presence or absence of an attachment.

Information on your n8n setup

• n8n version: cloud ver 1.11 (I think – latest stable as of Sat morning)
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app):
• Operating system:

I’ve been wrestling with this for a couple of days. I’m trying to ID if gmail items have an attachment based on an example from a book that I’ve moved on from hours ago. Many variants of the expression below, some boolean, some numeric, always resulting in ‘false’ even if there’s an attachment.

{{ Object.keys($binary || {}).some(k => k.startsWith(‘attachment_’) && $binary[k]?.data?.length > 0) ? 1 : 0 }}

Is there a more efficient method of identifying mail items with attachments? The book mentioned there’s a setting options in the email trigger for ‘only attachments is true’ but., that seems to be old information as I wasn’t able to find it.

thanks for any help anyone can provide.

{{ $binary.keys().length }}

should do the trick to identify

• if there is one attachment:= 1.
• if there is at least 1: > 0

thank you, sir. This looks much more straight forward. KISS principle remains king. I’ll give this a try shortly. I have found an alternat work around which is functional; but, I’m definitely interested in getting the if node working correctly.
