ClickHouse Node.js Client Troubleshooting

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

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.
