URL Fetch AssertionError：2

Question

使用异步URL Fetch时，我会收到如下的间歇性错误：

对于300次提取，我得到了大约20篇论文。难道我做错了什么？或者这是一个错误吗？

Traceback (most recent call last):

AssertionError: 2

在 init ：

中

self.fetcher = urlfetch.create_rpc(deadline=60)

在多次调用的方法中： 也排除错误：

fetch = urlfetch.make_fetch_call(
  self.fetcher,
  'https://email.us-east-1.amazonaws.com/',
  payload=form_data,
  method=urlfetch.POST,
  headers=self.headers,
)

我想我应该创建一个新的rpc而不是重用它？

显示一些代码，从错误中看起来您正在重用现有的活动RPC对象。
