Error in Flask App deployment using Zappa

Question

I am very new in zappa. Currently I am trying to deploy my flask project using zappa.

While deploying my Flask app I get this error

Traceback (most recent call last):

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

Does anyone know why this error is coming or how I can resolve this?

Answer 1

I don't know much about zappa, but the error message clearly states your problem:

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

It seems to me that you haven't set the parameter restApiId, which should contain a value of type basestring. I'm not sure what that parameter is about, but it seems to have to do something with the AWS-CLI.

Answer 2

In your aws cli be sure you are utilizing the IAM that you created for the zappa function, then follow the aws configure q&a for access key, secret key and region. I would suggest that you follow this very helpful tutotial that takes it step by step: https://developer.amazon.com/blogs/post/8e8ad73a-99e9-4c0f-a7b3-60f92287b0bf/new-alexa-tutorial-deploy-flask-ask-skills-to-aws-lambda-with-zappa I really hope this is helpful.
