javascript - Puppeteer 键入触发 aws lambda 中的错误

问题描述

我正在创建一个在 AWS Lambda 函数上运行的抓取，但是当我在站点上键入查询时，它会触发一个错误，我无法在我的本地环境中重现该错误。有谁知道会是什么？

代码：

query: async (name, birthDate, cpf) => {
    logger.info('QUERY_PARAMS_AP', '', [name, birthDate, cpf]);
    try {
      await page.waitFor(5000);

      await page.type('input[id="formNome"]', name);
      await page.type('input[id="formDataDeNascimento"]', birthDate);
      await page.type('input[id="formCpf"]', cpf);
      ...

该错误是在 page.type 方法中触发的。

触发错误如下：

{ Error: Protocol error (Input.dispatchKeyEvent): Target closed.
