parsing focus options: %w

Error message

parsing focus options: %w

What it means

Options passed to frame.focus(selector, opts) failed to parse (frame_mapping.go:107). FrameBaseOptions.Parse reads only 'strict' and 'timeout' and always returns nil in this codebase - this wrapper is defensive and effectively unreachable in the current version.

Solutions

1. Use supported keys only: { timeout: 3000, strict: true }
2. If it fires on stock k6, report it with the script and k6 version

const safeOpts = { timeout: Number(opts?.timeout) || undefined, strict: !!opts?.strict };

try {
  await frame.focus(sel, safeOpts);
} catch (e) {
  console.error(`focus(${sel}) failed: ${e.message}`);
}

When it happens

Trigger: No focus option value can trigger it today; both keys are coerced without erroring. Only an internal k6 change to the parser could make it fire.

Common situations: Essentially never hit on stock k6; relevant only when triaging k6 forks or unreleased parser changes.
