s3_sync exclude parameter does not work with folders

I am trying to use s3_sync to upload files from local git repository to S3 without the .git directory. I tried the exclude parameter with different variations such as “.git,.git/,.git*/*”

This is the line that I tested (with dummy values):

s3_sync: aws_access_key=“xxx” aws_secret_key=“xxx” bucket=“somes3bucket” file_root=/path/ exclude=“.git,.git/,.git*/*” mode=push delete=yes

Anyone has had any success with excluding folders?

Any thoughts or suggestions on what I can try?
