parsing getAttribute options: %w

Error message

parsing getAttribute options: %w

What it means

Options passed to frame.getAttribute(selector, name, opts) failed to parse (frame_mapping.go:125). Like focus, it uses FrameBaseOptions whose Parse always returns nil - a defensive, effectively unreachable branch in this version.

Solutions

1. Pass only { timeout, strict }
2. Report to k6 if it fires on a stock build

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

try {
  const v = await frame.getAttribute(sel, name, safeOpts);
  if (v == null) console.warn(`${sel} has no attribute ${name}`);
} catch (e) {
  console.error(`getAttribute(${sel}, ${name}) failed: ${e.message}`);
}

When it happens

Trigger: No getAttribute option ({ timeout, strict }) can trigger it today; values are coerced, never rejected.

Common situations: Not seen on stock k6; only relevant to forks or modified parsers.
