使用Zappa的Flask App部署中的錯誤

Question

我對zappa非常陌生。 目前，我正在嘗試使用zappa部署我的flask項目。

部署Flask應用程序時出現此錯誤

Traceback (most recent call last):

ParamValidationError: Parameter validation failed:
Invalid type for parameter restApiId, value: None, type: <type 'NoneType'>, valid types: <type 'basestring'>

有誰知道為什么會出現此錯誤，或者我該如何解決？

Answer 1

我對zappa不太了解，但是錯誤消息清楚地說明了您的問題：

Invalid type for parameter restApiId, value: None, type: <type 'NoneType'>, valid types: <type 'basestring'>

在我看來，您尚未設置參數restApiId ，該參數應包含basestring類型的值。 我不確定該參數是關於什么的，但是似乎必須對AWS-CLI做些事情。

Answer 2

在aws cli中，請確保您正在使用為zappa函數創建的IAM，然后按照aws對訪問密鑰，私鑰和區域進行配置。 我建議您遵循此非常有用的指導原則，並逐步進行： https : //developer.amazon.com/blogs/post/8e8ad73a-99e9-4c0f-a7b3-60f92287b0bf/new-alexa-tutorial-deploy-flask向zappa的aws-lambda詢問技能，我真的希望這會有所幫助。
