invalid duration: %w

Error message

invalid duration: %w

What it means

Returned by ConfigureByDSN when the 'delay_for' query parameter of a loki:// DSN cannot be parsed as a Go duration string (e.g. '5x' or 'abc'). Wraps time.ParseDuration; the value must also be within 0–5s to pass the follow-up range check.

Solutions

1. Use a duration with unit, e.g. delay_for=1s, delay_for=500ms
2. Values must be between 0 and 5 seconds
