scenario %s has configuration errors: %s

Error message

scenario %s has configuration errors: %s

What it means

Aggregating error from ScenarioConfigs.Validate: it runs each scenario's own Validate and, when any scenario returns validation errors, wraps them all (joined with commas) under the scenario's name. The real cause is in the nested errors.

// GetSortedConfigs returns a slice with the executor configurations,
// sorted in a consistent and predictable manner. It is useful when we want or
// have to avoid using maps with string keys (and tons of string lookups in
// them) and avoid the unpredictable iterations over Go maps. Slices allow us
// constant-time lookups and ordered iterations.
//
// The configs in the returned slice will be sorted by their start times in an
// ascending order, and alphabetically by their names (which are unique) if
// there are ties.

Solutions

1. Read the nested error details to find which scenario option is invalid
2. Fix each reported scenario's options (VU counts, durations, rates, stages)
3. Re-run k6 until per-scenario validation passes
