Wrong Type Hint on some keywords. (locator: Union[WebElement, None, str])

[Snooz82]

Some keywords like Capture Element Screenshot do have a type hint, that allows WebElement, None and str.
But the None is actually wrong.
There are some keywords that actually would work with ${None} as a locator, but this one and others actually does not work and raises the error TypeError: expected string or bytes-like object, got 'NoneType'

Fix would be to just remove the None.

René do you have a list of keywords you discovered that this affects?

[Snooz82]

Not at directly.
I remembered that it was more than one.
search for those which has None as type hint, but no default.

A quick search results in the following you should check.

• Get Table Cell
• Table Column Should Contain
• Table Footer Should Contain
• Table Header Should Contain
• Table Row Should Contain
• Table Should Contain
• Wait Until Element Contains
• Wait Until Element Does Not Contain
• Wait Until Element Is Enabled
• Wait Until Element Is Not Visible
• Wait Until Element Is Visible
• Wait Until Page Contains Element
• Wait Until Page Does Not Contain Element
• Capture Element Screenshot

But there may be more.
All those have None as type hint for locator but no None as default.
