Question

我对AWS Lambda容器和Scrapy有问题。

当我使用SAM在本地执行代码时，它永远不会失败，但是在短时间内两次在AWS Lambda容器中执行代码时，会产生此错误：

我的Lambda的代码是：

import logging
import scrapy


logging.getLogger().handlers = [] # Necessary to manage the Log Level of Scrapy in AWS Lambda 

def handler(event, context):  # Lambda entry point

    # SPIDER

    settings = {
            'LOG_ENABLED': True,
            'LOG_LEVEL': 'ERROR'
            }

    process = CrawlerProcess(settings=settings)    

    process.crawl(Spider)
    process.start()

就像Crawler Process已经在重用容器中运行并且失败了（或另一个Scrapy Process）一样。有帮助吗？
