Definition

interface ErrorContext

Field structure

Field	Type	Required	Description
stageId	string | undefined	Optional	Read-only. Stage that first observed the error; later annotations keep the earliest value.
codes	readonly string[] | undefined	Optional	Read-only. Codes contributed by the boundary, merged with those found on the error itself.
isRetryable	boolean | undefined	Optional	Read-only. Retryability asserted by the boundary; omitted when it cannot be determined.

Using the type

Read the contract at the call site

TypeScript

import type { ErrorContext } from '@jangts/agent-core/errors';

// Keep the original contract at the call site; TS and JS share the same runtime behavior.
function inspect(value: ErrorContext) {
  return value.stageId;
}

JavaScript

/** @param {import('@jangts/agent-core/errors').ErrorContext} value */
function inspect(value) {
  return value.stageId;
}
