When Linear returns an HTTP 400 response code due to excessive depth or query nesting, what is the value of extensions.type in the GraphQL error payload?
| Checked | Without skill | With skill |
|---|---|---|
| The extensions.type value is specified as query_error. | Missed | Passed |
The instructions your model reads when the skill loads.
Quick reference for diagnosing and resolving common Linear API and SDK errors. Linear's GraphQL API returns errors in response.errors[] with extensions.type and extensions.userPresentableMessage fields. HTTP 200 responses can still contain partial errors -- always check the errors array.
// Linear GraphQL error shape
interface LinearGraphQLResponse {
data: Record<string, any> | null;
errors?: Array<{
message: string;
path?: string[];
extensions: {
type: string; // "authentication_error", "forbidden", "ratelimited", etc.
userPresentableMessage?: string;
};
}>;
}
// SDK throws these typed errors
import { LinearError, InvalidInputLinearError } from "@linear/sdk";
// LinearError includes: .status, .message, .type, .query, .variables
// InvalidInputLinearError extends LinearError for mutation input errors
// extensions.type: "authentication_error"
