parsing inner text options

Error message

parsing inner text options: %w

What it means

Thrown synchronously when the options argument to locator.innerText() fails to parse. The mapping (locator_mapping.go:314-318) builds common.FrameInnerTextOptions (FrameBaseOptions) and wraps Parse errors as "parsing inner text options: %w". Parse only reads strict/timeout with coercing accessors, so a genuine failure means sobek raised reading the object — throwing getter, Proxy trap, or a value whose numeric coercion throws.

Solutions

1. Use a plain literal: locator.innerText({ timeout: 5000 }) or omit options
2. Precompute dynamic values into plain properties
3. Do not pass Proxy/accessor objects to the browser module
4. try/catch the call to capture the failure with context

Example fix

// before
await locator.innerText(lazyOpts); // getter throws

// after
await locator.innerText({ timeout: lazyOpts.timeout }); // property read happens safely first

function isPlainBaseOptions(o) {
  return o == null || (typeof o === 'object' &&
    (o.timeout === undefined || typeof o.timeout === 'number') &&
    (o.strict === undefined || typeof o.strict === 'boolean'));
}

try {
  const text = await locator.innerText(opts);
} catch (e) {
  throw new Error(`innerText failed (ensure options are plain data): ${e}`);
}

When it happens

Trigger: opts with a getter for timeout/strict that raises; Proxy options with throwing traps; a non-number timeout with a throwing toPrimitive/valueOf.

Common situations: Text-extraction helpers that build options from lazily-validated config; debugging Proxies over arguments; ported Playwright utilities that decorate options.
