ClickHouse Node.js Client Troubleshooting

Reference: https://clickhouse.com/docs/integrations/javascript

⚠️ Node.js runtime only. This skill covers the @clickhouse/client package running in a Node.js runtime exclusively — including Next.js Node runtime API routes, React Server Components, Server Actions, and standard Node.js processes. Do not apply this skill to browser client components, Web Workers, Next.js Edge runtime, Cloudflare Workers, or any usage of @clickhouse/client-web. For browser/edge environments, the correct package is @clickhouse/client-web.

How to Use This Skill

1. Identify the issue — match symptoms to the Issue Index below and read the corresponding reference file.
2. Lead with the diagnosis — explain what's likely causing the issue before giving the fix.
3. Note version constraints — flag if a fix requires a minimum client version and check it against what the user provided.
4. Ask only what's missing — if the fix is version-dependent and you don't know their version, ask; otherwise help immediately.
