Clickhouse Js Node Troubleshooting

description: >
  Troubleshoot and resolve common issues with the ClickHouse Node.js client
  (@clickhouse/client). Use this skill whenever a user reports errors, unexpected
  behavior, or configuration questions involving the Node.js client specifically —
  including socket hang-up errors, Keep-Alive problems, stream handling issues, data
  type mismatches, read-only user restrictions, proxy/TLS setup problems, or long-running
  query timeouts. Trigger even when the user hasn't precisely named the issue; vague
  symptoms like "my inserts keep failing" or "connection drops randomly" in a Node.js
  context are strong signals to use this skill. Do NOT use for browser/Web client issues.

Do **not** apply this skill to browser client components, Web Workers, **Next.js Edge runtime**, Cloudflare Workers, or any usage of `@clickhouse/client-web`.
