double clicking on x:%f y:%f: %w

Error message

double clicking on x:%f y:%f: %w

What it means

Thrown by Mouse.DblClick(x, y) when the underlying double-click sequence fails. It delegates to the same internal click() as Click, but performs the sequence twice in quick succession, making it more sensitive to state changes between clicks (navigation, overlay appearing, session close) and to CDP dispatch failures.

Solutions

1. Recompute coordinates from a fresh boundingBox() right before the call
2. Ensure the target action does not navigate between the two clicks, or use elementHandle.dblclick() instead of raw mouse coordinates
3. Verify the page is still open (page.isClosed()) before dispatching
4. Wrap in try/catch and retry once after re-locating the element

Example fix

// before
const box = await page.locator('tr.row').boundingBox();
await page.mouse.dblclick(box.x, box.y);

// after
const row = page.locator('tr.row');
await row.waitFor();
await row.dblclick(); // selector-based, auto-resolves and retries

if (page.isClosed()) throw new Error('page closed');
const box = await page.locator('tr.row').boundingBox();
if (!box) throw new Error('row not measurable');
await page.mouse.dblclick(box.x + box.width / 2, box.y + box.height / 2);

try {
  await page.mouse.dblclick(x, y);
} catch (e) {
  if (/target closed|session/i.test(e.message)) { /* recreate page, restart */ }
  else throw e;
}

When it happens

Trigger: mouse.dblclick(x, y) where the page navigates or the session drops between the two click cycles; an overlay appears after the first click and the second dispatch fails; browser crash during the sequence.

Common situations: Double-clicking rows in data grids that open a detail view (navigation between clicks); double-click triggering a modal that invalidates subsequent coordinates; reusing stale boundingBox coordinates.
