finding offset position: %w

Error message

finding offset position: %w

What it means

offsetPosition() calls BoundingBox() to anchor an offset-based click/hover point; this error wraps that failure. The wrapped error is usually 'element is not visible: ... Could not compute box model' for hidden, zero-layout, or detached elements.

Solutions

1. Wait for the element to be visible first (waitForSelector state 'visible')
2. Re-locate the element right before the action
3. Use { force: true } to skip actionability checks when the hidden state is intentional
4. Verify the position coordinates fall inside the element's box

Example fix

// before
await handle.click({ position: { x: 5, y: 5 } }); // finding offset position: element is not visible

// after
await page.waitForSelector('#btn', { state: 'visible' });
await (await page.$('#btn')).click({ position: { x: 5, y: 5 } });

const box = await handle.boundingBox();
if (!box || box.width === 0 || box.height === 0) {
  await page.waitForSelector(sel, { state: 'visible' });
}
await handle.click({ position: { x: 5, y: 5 } });

try {
  await handle.click({ position: pos });
} catch (e) {
  if (String(e).includes('finding offset position')) {
    await handle.click(); // retry at center
  } else { throw e; }
}

When it happens

Trigger: click()/dblclick()/hover() with a `position` option on an element that is display:none, has zero size, was detached, or whose bounding box otherwise cannot be computed.

Common situations: Offset-clicking before the element renders; element inside a collapsed iframe; stale handle after navigation; position coordinates outside the element on tiny elements.
