AWS 网关无服务器 { "message" ： "Internal server error" }

Question

我创建了一个AWS API网关Lambda。在无服务器部署之后，当我试图获取端点时，它会不断返回{quot；消息"："内部服务器错误"}这个错误。我尝试了从网上找到的多种解决方案，但都无济于事。我不确定我是否为处理程序做得正确。。。。从昨天早上起我就一直困在家里。非常感谢。

确保API网关具有调用Lambda。。。

如果这还不能解决问题，请查看CloudWatch以了解Lambda日志组中的任何错误。请确保CloudWatch日志也已启用。。

对我来说，这是因为内存有限。当我增加memorySize时，开始工作得很好
