--json argument no longer works #408
Description
Hello,
I have been using WARP 1.0.8 with --json which:
- removes the progress bar
- outputs a clean json output which is easy enough to post process in code.
Any subsequent versions have the json output not working anymore.
Is this broken or did the arguments change? The readme never really declared the --json flag
Expected output example:
warp list --objects 1000000 --obj.size 256B --host=xxxx --access-key="xxxx" --secret-key="xxx" --tls --insecure --concurrent 150 --duration 10m --noclear --json
