Problems with sending a Gmail with a Dropbox file as attachment

1. I receive an email via Gmail Trigger.
2. The AI Agent checks what kind of file is needed.
3. The file is downloaded from Dropbox.
4. Then the file is sent back via Gmail with the file attached.

But I keep getting this error:

Cannot read property '0' (item 0)
Or: the attachment field shows [undefined].

But it doesn’t work. Dropbox step is green and outputs fine (I tested it), and the file shows in output. I think I’m missing something with how to pass it correctly to the Gmail node.

Here’s a screenshot of my current setup and what the AI tool returns.

Any help would be awesome

Not sure about the AI Agent node can work with binary download from one tool ans pass to another tool.

A more safety way could be something like this

Using the AI to determine which file to download and download yourself then send the email.
