我想知道如何查看 errorMessage [object Object]？

解决方案

我希望现在还不算晚。我遇到了同样的问题，我按照以下链接中的说明解决了这个问题：

“在调用回调退出函数之前，您必须将 myErrorObj 对象转换为 JSON 字符串。否则，myErrorObj 将作为“[object Object]”的字符串返回。”

https://docs.aws.amazon.com/apigateway/latest/developerguide/handle-errors-in-lambda-integration.html

我只是将“错误”对象作为 JSON.stringify(error) 传递，解决了我的问题。

希望它有所帮助。

问候
