TypeError : coercing to Unicode : need string or buffer, NoneType found

[Rony]

Hi,

When i execute script in IE8 its working as expected.But it creates problem when i try to run in IE9.
Robot Framework displays the error- " TypeError: coercing to Unicode: need string or buffer, NoneType found".

What was the reason behind that...any one can tell...?

Please run with log level debug or trace and provide the keyword that failed along with all messages logged under that keyword.

Hi Kevin O,

Many thanks for your reply.

Yes i can now run some of my cases but still i am facing some sort of problem like-
Element xpath=//input[@id="Create Object" or @name="Create Object" or @value="Create Object" or @src="Create Object" not found.

This error was showing when try to execute the following line...

Click Image (selenium built in keyword)- ${Function_Name} (Argument-locator)-don't wait (optional argument-locator)

Waiting for your reply.

Maybe the object is not there when you expect it? Try Wait Until Page Contains Element.

Also if your element is inside a frame or iframe, you need to switch to that frame first before Selenium will "see" the element.
