Frames aren't scrollable. If you read the documentation for the Frame widget you'll see that it confirms the error message: frames don' t have a `yscrollcommand` option. — Bryan Oakley, Oct 01 '20 at 14:01

Unfortunately, we can't add scrollbars to frame in Tkinter we have to use canvas for that

Refer this: tkinter: using scrollbars on a canvas
