HI Team,

I had run a load test and i see results in negative. why is it so ? In "min" its showing as "-6" and also mean is null

  "http.response_time": {
    "min": -6,
    "max": 29420,
    "count": 218984,
    "mean": null,
    "p50": 22,
    "median": 22,
    "p75": 98.5,
    "p90": 407.5,
    "p95": 608,
    "p99": 1249.1,
    "p999": 1408.4

One more thing. I see result file around 20MB. If i am running for a longer duration the result file will be in GB. How do i reduce it ?

thanks @nithinkadam19. This looks like a bug, we'll investigate.

We've added some assertions to our test suite to catch this, but so far it hasn't appeared. Would you be able to share any more details about your test? For example:

Thank you!
