Errors

Syntax, validation, execution, pagination, and query-cost errors normally return HTTP 200 with an errors array. Data may be partial, so handle both keys independently.

{
  "data": { "orders": null },
  "errors": [
    { "message": "...", "path": ["orders"] }
  ]
}

Business and input failures are generally returned inside the mutation payload. Always requestuserErrors { message field } when it is available.

mutation CreateOrder($input: OrderCreateInput!) {
  orderCreate(input: $input) {
    order { id }
    userErrors { message field }
  }
}
