unknown query parameter: %s

Error message

unknown query parameter: %s

What it means

Strict query-parameter whitelist in the InfluxDB output's ParseURL: every key in the output URL's query string must match one of the known parameters (insecure, payload_size, consistency, pushInterval, concurrentWrites, tagsAsFields, and similar). This error reports the first unrecognized key, protecting against typos silently disabling intended configuration — e.g., pushingInterval instead of pushInterval.

Solutions

1. Check the parameter name for typos against the k6 InfluxDB output documentation
2. Move unsupported parameters out of the K6_INFLUXDB_ADDR URL
3. Use the corresponding environment variables (K6_INFLUXDB_PUSH_INTERVAL, etc.) or -o influxdb settings instead
