The function code size is larger than the maximum allowed size for functions that are triggered by a CloudFront event

Hi there,

we are trying to get this example app running but are unable to deploy, because the resulting Lambda function is too large.

Resource handler returned message: "Invalid request provided: AWS::CloudFront::Distribution: The function code size is larger than the maximum allowed size for functions that are triggered by a CloudFront event: 1212049 Max allowed: 1048576 Function: arn:aws:lambda:us-east-1:xxxxxxxxxxx:function:yyyyyyyyyyyyyyyyyyyyyy-CloudFrontAuthFunction-wykPqdDXOu0C:1 (Service: CloudFront, Status Code: 400, Request ID: ...

We didn't touch the JS code nor the package.json file.

Can anyone reproduce this? What can we do?

Thanks in advance,
Florian.

At least we could verify that the code works after "manually" removing a bunch of unnecessary files between build and package:

	find build/CloudFrontAuthFunction/node_modules -iname '*.d.ts' -delete
	find build/CloudFrontAuthFunction/node_modules -iname '*.md' -delete
	find build/CloudFrontAuthFunction/node_modules -iname '*.txt' -delete
	find build/CloudFrontAuthFunction/node_modules -iname 'license' -delete
	rm -r `find build/CloudFrontAuthFunction/node_modules -name "test" -type d`
	rm -r build/CloudFrontAuthFunction/node_modules/axios/dist

@workflo Thank you for opening this issue. We will work on condensing the node_modules to meet the limitations on the function size.

Any updates on progress? I've got a project at my workplace where I need to gate my CF-distributed site with an OIDC provider and got excited at this project.

I attempted to webpack this function but cant seem to get it lower than 1.1 MB (compressed). I am admittedly inexperienced with webpack, though.

@workflo and @concordion2k thank you for opening-up this issue. Let me know if there are still any issues after doing the following:

1. Pull the latest from the master branch by running git pull.
2. Delete your existing build directory.
3. Re-run the deployment steps outlined in the README

Let me know if you have any questions!
