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 @pinecone-database/n8n-nodes-pinecone-assistant is verified or supports 3.0 (used in Get context snippets in Pinecone Assistant).
