could not load and configure the test: %w

Error message

could not load and configure the test: %w

What it means

In the --local-execution path of `k6 cloud run`, the test is loaded and configured by loadAndConfigureLocalTest (using getCloudRunLocalExecutionConfig); any failure is wrapped with this message. The wrapped cause is the ordinary test-loading pipeline, so it ranges from file and syntax errors to invalid options, bad env-var config, or a missing default export.

Solutions

1. Run `k6 run script.js` (or `k6 inspect script.js`) locally to surface the exact underlying error
2. Fix the reported script issue: path, syntax, imports, missing default export
3. Validate options and any --config file / K6_* env overrides named in the wrapped error

Example fix

// before: script.js exports nothing
const http = require('k6/http')
// after
const http = require('k6/http')
export default function () { http.get('https://test.k6.io') }

// pre-flight: the script must at least load
if err := exec.Command("k6", "inspect", "script.js").Run(); err != nil {
    log.Fatalf("script.js does not load: %v", err)
}
// then: k6 cloud run --local-execution script.js

test, err := loadAndConfigureLocalTest(gs, cmd, args, getCloudRunLocalExecutionConfig)
if err != nil {
    return fmt.Errorf("could not load and configure the test: %w", err)
    // unwrap with errors.Unwrap in callers to distinguish file vs options vs env errors
}

When it happens

Trigger: Running `k6 cloud run --local-execution script.js` where the file does not exist, contains a JavaScript syntax or import error, exports no default function, has invalid options (scenarios, thresholds), or where a K6_* env var / --config file fails validation.

Common situations: Path typos or wrong working directory in CI; a script that runs under `k6 run` on an older k6 but uses options the newer cloud-run config rejects; env vars like K6_CLOUD_TIMEOUT set to non-durations; broken imports after dependency changes.
