GraphQL Query Syntax Error After Refactoring
After Cursor refactored your GraphQL queries, queries are rejected with syntax errors or field not found errors. GraphQL queries that were working no longer execute.
Query syntax or schema expectations were changed incorrectly.
Error Messages You Might See
GraphQL syntax error
Unknown field
Variable type mismatch
Query validation failed
Common Causes
- Field name changed but query not updated
- Query syntax invalid (missing braces, parentheses)
- Variables not properly defined or used
- Fragment syntax broken after refactor
- Alias syntax incorrect or missing
How to Fix It
Validate query syntax in GraphQL playground/IDE. Check schema for actual field names. Variables: query GetUser($id: ID!) { user(id: $id) { name } }. Verify endpoint URL. Check for query errors in response under 'errors' key.

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

How do I use variables in GraphQL?
Define in query signature: query GetUser($id: ID!). Pass in variables object. Prevents string injection.
What's a GraphQL fragment?
Reusable selection set. Reduces duplication: fragment UserFields on User { id name }. Use in queries.
