I used export source code w/ function Configurations.
aws lambda get-function --function-name $name | tee ./code/$name.json | jq -r '.Code.Location' | xargs wget -O ./code/$name.zip

It's not working for me, just generating the folder "code"; nothing else.

Using Wget didnt worked really well for me i instead replaced it by curl and it works well
aws lambda get-function --function-name $name | tee ./code/$name.json | jq -r '.Code.Location' | xargs curl --output ./code/$name.zip
