WorkflowContractError

CORE · class · 运行时值

The workflow definition violates Core's execution contract, as opposed to failing business logic.

Examples: unknown model binding, asynchronous predicate, unmatched route, missing state field. It is a programming error, so callers should not treat it as retryable.

入门 · Node.js

TypeScript

import { AttemptBudget } from '@jangts/agent-core/engine';
const attempts = new AttemptBudget(2);
while (attempts.take()) console.log('attempt', attempts.used);
console.log(attempts.available); // false

JavaScript

import { AttemptBudget } from '@jangts/agent-core/engine';
