Hi @21.prash,
the main reason why you’re seeing the reported error is the following option:
K6_INFLUXDB_PUSH_INTERVAL=20s
Why did you set it so high? In this way, you’re saying to the output to aggregate samples across 20 seconds and flush all at once. You should definitely use a lower value. The default value is 1s.
You should also consider migrating to the new official Docker image grafana/k6.
