Redux API中间件throws fetch未定义

我最近升级了 redux-api-middleware 运行测试时从2.3.0到3.0.1 jest@22.2.1 我明白了 ReferenceError :

ReferenceError: fetch is not defined

  19 | export function sortPolicyChain (payload: Array<ChainPolicy>): SortPolicyChainAction {
  20 |   return { type: 'SORT_POLICY_CHAIN', payload }
> 21 | }
  22 |
  23 | export type UpdatePolicyInChainAction = { type: 'UPDATE_POLICY_IN_CHAIN', policyConfig: ChainPolicy }
  24 | export function updatePolicyInChain (policyConfig: ChainPolicy): UpdatePolicyInChainAction {

  at Object.<anonymous> (node_modules/redux-api-middleware/lib/index.cjs.js:404:3)
  at Object.<anonymous> (app/javascript/src/Policies/actions/PolicyChain.jsx:21:27)
  at Object.<anonymous> (spec/javascripts/Policies/actions/PolicyChain.spec.jsx:3:20)

stacktrace指向此行 保险单 :

export function fetchChain (serviceId: string): RSSAAction {
  return {
    [RSAA]: {
      endpoint: `/admin/api/services/${serviceId}/proxy/policies.json`,
      method: 'GET',
      credentials: 'same-origin',
      types: [REQUEST, SUCCESS, FAILURE]
    }
  }
}

根据 documentation here :

如果提供,fetch选项必须是符合 获取API。 否则,将使用全局获取。

但似乎找不到全局获取。有什么想法吗?
