Understanding Error distribution & Status Code distribution in hey output

[ankitanallana-livongo]

So, I was just running some load testing with hey for an application locally and in my result I see this:

% hey -n 500 -c 10 -m GET -H "Authorization: Bearer $TOKEN" -H 'Content-Type: application/json' -d '{"memberId":"1800"}' http://localhost:30001/path

Status code distribution:
  [200]	250 responses

Error distribution:
  [250]	Get "http://localhost:30001/signals": EOF

I ran the test with 500 requests, why does it say 250 responses in Status Code distribution? And what does Error distribution mean? The EOF bit doesn't tell me much. Were 500 or 250 tests run in the end?

It was 500. 250 responses in Status code distribution + 250 from Error distribution cmiiw
