Multiple binary files, how to reference all of them in next node?

[Jayavel]

Describe the problem/error/question

I have a webhook node that gets multiple binary files as input from another service. I have named the files “upload” in the service I use, but when receiving the files in n8n, they show up as “upload0”, “upload1”, “upload2”, and so on. Now, I plan to use the “Read PDF” node to read the contents of the files. This doesn’t work, and it shows an error. Not only in the Read PDF node, but I also plan to send these files separately to another service (Gotenberg) through HTTP Request if I get files in the webhook in formats other than PDF. But, I would first like to get a basic version up and running.

Webhook node output:

Read PDF node output:

What is the error message (if any)?

ERROR: Cannot read properties of undefined (reading 'id')

Please share your workflow

Share the output returned by the last node

Split binary file data into individual items - Attachments from mail

Hey @idar, Welcome to the community Assuming you are using the new code node and have it set to Run Once for All Items using the below should do the job. let results = []; for (const item of $input.all()) { for (key of Object.keys(item.binary)) { results.push({ json: { fileName: item.binary[key].fileName }, binary: { data: item.binary[key], } }); } } return results;
