How to access or pass n8n Form Trigger's document through subsequent nodes?

Help me Build my Workflow
1

First time here, hello everyone :slight_smile:

I would like to create a work flow, where a PDF can be uploaded and its full text extracted for later classification. However, there are scanned PDFs as well, so I need OCR first. To reduce time and cost, I only want to send documents with empty extracted text to Azure Document Intelligence:

Passing the “Dokument” property from the Form Trigger to Extract from file works fine by entering “Dokument” as Input Binary Field:

However, I cannot connect the “Dokument” property of the Form Trigger with the Azure Document Intelligence node:

I tried using a formula as well, but neither item, item.binary, item.json nor item.json.Dokument work:

I saw similar questions regarding the availabilty of the actual document uploaded in subsequent nodes, but no definite answer or explanation.

Any help would be greatly appreciated!

Just use the “Merge” node in Combine mode to have the binary data available after the if node:
