local file picker example error on nicegui 2.1.0

[zak-45]

Description

Hi,

just tested the local_file_picker example and got this error when click on OK after selected a file :

JavaScript did not respond within 1.0 s

Traceback (most recent call last):
  File "C:\Program Files\Python311\Lib\asyncio\tasks.py", line 500, in wait_for
    return fut.result()
           ^^^^^^^^^^^^
  File "C:\Program Files\Python311\Lib\asyncio\locks.py", line 213, in wait
    await fut
asyncio.exceptions.CancelledError

The above exception was the direct cause of the following exception:

  File "C:\Users\zak-4\PycharmProjects\WLEDVideoSync\.venv\Lib\site-packages\nicegui\javascript_request.py", line 26, in __await__

  File "C:\Program Files\Python311\Lib\asyncio\tasks.py", line 502, in wait_for

TimeoutError

The above exception was the direct cause of the following exception:

TimeoutError: JavaScript did not respond within 1.0 s

The double-click work as expected....

This not happened on nicegui 1.4.37, where all is functional.

OS version: win 11
Python : 3.11 x64

Have seen some breaking changes.
looks like this solve the problem :

    async def _handle_ok(self):
        await ui.context.client.connected()
        rows = await self.grid.get_selected_rows()
        # rows = await ui.run_javascript(f'getElement({self.grid.id}).gridOptions.api.getSelectedRows()')
        self.submit([r['path'] for r in rows])

need to put

         rows = await self.grid.get_selected_rows()

instead

        rows = await ui.run_javascript(f'getElement({self.grid.id}).gridOptions.api.getSelectedRows()')
