ValueError: Argument 'url' got value 'https://www.google.com' that cannot be converted to None

when I run the robot script in pycharm getting below error
ValueError: Argument ‘url’ got value ‘https://www.google.com’ that cannot be converted to None.

@vijay1980 I don’t think Selenium2Library is supported anymore. You should instead use SeleniumLibrary

I don’t know why you used Open_browser instead of Open Browser which is the correct keyword.

Try with the correct name.

The name shouldn’t be an issue here.

As far as I am aware Robotframework is simply making underscores in the python method into spaces. So calling Open Browser or open_browser or seleniumLibrary.open_browser should all get you to the same place.

I only mentioned because the error is suggesting expecting None for url, and that makes me think the user is using a different keyword.
