Services it uses
Before you upgrade to n8n 3.0
We can't fully verify this one: it relies on 1 community package, and n8n 3.0 turns unverified community packages off by default (N8N_UNVERIFIED_PACKAGES_ENABLED=false).
- Check that n8n-nodes-pdf-api-hub is verified or supports 3.0 (used in Extract Claim Data, Generate Approval Letter, Sign Approval Letter).
- Also check Gmail Trigger below v1.4 runs as v1.4 (drafts skipped, max emails per poll).
