commands I tried.
curl -L https://github.com/sigscalr/ss-pub-data/releases/download/v1.0.0/prod-data-100mb.json.tar.gz -o prod-data-100mb.json.tar.gz
tar -xjOf prod-data-100mb.json.tar.gz > prod-data-100mb.json
curl http://localhost:8081/elastic/_bulk -i --data-binary "@prod-data-100mb.json"

the client does work though.

curl http://localhost:8081/elastic/_bulk -i --data-binary "@prod-data-100mb.json"
