s3 HTML metadata problem (Dec 9, 2020)

After finally solving all of my refresh/routing problems between s3, cloudfront and react, the s3 bucket changed its handling of .html files when their extension isn't provided. The "fix" is to update the Content-Type metadata post-upload. Since I'm using buddy.works for my CI pipeline, I added a new AWS CLI step to the pipeline with the following commands

aws s3 cp \
      --exclude "*" \
      --include "blog/*" \
      --content-type="text/html"  \
      --metadata-directive="REPLACE" \
      --recursive
      
aws s3 cp \
      --exclude "*" \
      --include "404" \
      --content-type="text/html"  \
      --metadata-directive="REPLACE" \
      --recursive
