Services it uses
Before you upgrade to n8n 3.0
We can't fully verify this one: it relies on 2 community packages, and n8n 3.0 turns unverified community packages off by default (N8N_UNVERIFIED_PACKAGES_ENABLED=false).
- Check that n8n-nodes-tesseractjs is verified or supports 3.0 (used in Tesseract).
- Check that n8n-nodes-pdf-page-extract is verified or supports 3.0 (used in PDF Page Extract).
