[Python] SeleniumBase CDP mode execute_script and evaluate with javascript gives error...

I am using SeleniumBase in CDP Mode.

I am having a hard time figuring out if this a python issue or SeleniumBase issue.

The below simple example shows my problem:

from seleniumbase import SB

with SB(uc=True, locale_code="en", headless=True) as sb:

link = "https://news.ycombinator.com"

print(f"\nOpening https://stackoverflow.com/questions/79414070/seleniumbase-cdp-mode-execute-script-and-evaluate-with-javascript-gives-error-s")

sb.wait_for_ready_state_complete(timeout=120)

sb.activate_cdp_mode(link)

script = f"""
function getSomeValue() {{
return '42';
}}

return getSomeValue();
"""

# data = sb.execute_script(script)
data = sb.cdp.evaluate(script)

print(data)

print("Finished!")


This throws error:

seleniumbase.undetected.cdp_driver.connection.ProtocolException:
exceptionId: 1
text: Uncaught
lineNumber: 5
columnNumber: 4
scriptId: 6
exception:
type: object
subtype: error
className: SyntaxError
description: SyntaxError: Illegal return statement
objectId: 3089353218542582072.1.2


Notice above that I have tried both sb.execute_script(script) and sb.cdp.evaluate(script) and both give the same issue.

How can I execute such scripts?
