'CodeUri' is not a valid S3 Uri of the form 's3://bucket/key

[tomvo]

Hi there,

I'm trying to get Lambda@edge working on eu-west and following your comments and library. Everything seemed to have installed fine and now i'm trying to get this example: https://aws.amazon.com/blogs/networking-and-content-delivery/resizing-images-with-amazon-cloudfront-lambdaedge-aws-cdn-blog/, working on eu-west-1 but i'm running into a lot of problems.

See here my full template. Any idea on what could be the issue?
