Question: Is it possible to configure CORS?

[WalternativE]

Hi, y'all! First of all thanks for your great work. My first time using AWS Lambda tooling and I'm really enjoying the experience so far 😊

My question because I didn't really find anything in the docs (which makes sense as the product is rather new): is it possible to configure CORS for the local RIE docker container which holds my custom function? Once it is deployed I'd imagine you would configure this directly in AWS but until then I currently don't see a way how I'd tell it to set CORS headers.

It's not the biggest of problems, as I could just use another pass-through CORS proxy locally. I was just wondering whether this was already a supported scenario.

Thanks a lot in advance!

Still not resolved in 2023! 😭
This pull request did fix it for me: #84.

So I cloned the v1.13 release, make the changes from the PR, and re-made the binaries. So that I could simply add this line to my Dockerfile and it would work for my AWS lambda image.

RUN curl -Lo /usr/local/bin/aws-lambda-rie https://github.com/MecSimCalc/aws-lambda-runtime-interface-emulator/raw/msc-v1.13/bin/aws-lambda-rie && chmod +x /usr/local/bin/aws-lambda-rie

It's not ideal, but better than nothing...
