Frequently Asked Questions
Why do variables fail?
Type mismatches (string where Int expected) and missing required ($) fields cause 90% of variable errors. Formatting plus validation surfaces both before the request leaves.
Nested input objects?
Yes — complex input types indent and validate recursively. A 50-line filter object formats into readable structure.
Copy back to clients?
Yes — formatted variables paste into Apollo Studio, GraphiQL, and code. Keep a variables file per query for regression runs.
Do GraphQL variables upload?
No — formatting runs locally in your browser. Variables never leave your device.
