Cannot execute Supabase queries from n8n Cloud workflow. Supabase credential connects successfully (authentication verified). When executing Get a Row or Create a row operations, the node times out indefinitely. The workflow is published and other operations (Twilio, Claude API) work without issues. Connection timeout - node stays "thinking" indefinitely. Workflow: Webhook → HTTP Request (Claude) → HTTP Request (Twilio) → Supabase Get a Row. Supabase node is configured correctly but cannot execute. Related GitHub issues: #18379, #15239 - reported as n8n Cloud egress network issue. Supabase node does not complete execution (times out before returning output).
