VPC中的AWS Lambda函數無法將項目放入Dynamodb表中

Question

這是我不斷得到的錯誤

瘋狂的部分是我的代碼昨天運行良好。 現在突然之間，我的lambda函數似乎無法訪問dynamodb。 它們通過VPC端點連接，昨天運行良好。 這是我以前發生的事情，當我將它留在晚上過夜后，第二天才開始工作。 但是，這是不可接受的行為，我需要找出導致它的原因。

有任何想法嗎？

我無法簡單地使用新的vpc終結點功能來使其正常工作，所以我采用了使用nat網關的舊方法。 這是有關如何執行此操作的好鏈接： https : //gist.github.com/reggi/dc5f2620b7b4f515e68e46255ac042a7
