Can´t find element in uc-mode?

[Rapid1898-code]

Hello - i try to use uc-mode to open a website, enter some text and press a button using the following code -

from seleniumbase import SB
link = "https://www.textbooks.com/sell-textbooks.php"
wISBN = "1616143967"
with SB(uc=True, incognito=True, xvfb=True, headless=False) as sb:
  sb.uc_open_with_reconnect(link)
  sb.type('input[id="dHTxt"]', wISBN)
  sb.click('button[id="btnMainSearch"]')

But i get this error message:

(seleniumALL) C:\DEVNEU\Fiverr2025\TRY\andreia_marques>python test.py
Traceback (most recent call last):

seleniumbase.common.exceptions.NoSuchElementException: Message:
 Element {input[id="dHTxt"]} was not present after 10 seconds!

Why can´t the input-field not found / the button not pressed?

This script worked for me:

from seleniumbase import SB

with SB(uc=True) as sb:
    url = "https://www.textbooks.com/sell-textbooks.php"
    wISBN = "1337613924"
    sb.activate_cdp_mode(url)
    sb.type('input[id="dHTxt"]', wISBN)
    sb.click('button[id="btnMainSearch"]')
    sb.sleep(5)

Note that CDP Mode is the successor to regular UC Mode.
