How to use rich Traceback with raise errors?

[codenotworking]

I'm trying to use rich's Traceback with raise errors, but the documentation doesn't give an example on it (unless I missed one). Just for try/except blocks. This is what I have in psuedo-code:

from rich.console import Console

console = Console()

def some_function(something):
    if something == "foo":
        do_something()
    elif something == "bar":
        do_something_else()
    else:
        console.print_exception(show_locals=True)
        raise ValueError("You dun goofed.")

I receive the error ValueError: Value for 'trace' required if not called in except: block. I checked the documentation for rich.Traceback which states:
trace (Trace, optional) – A Trace object produced from extract. Defaults to None, which uses the last exception.. Unfortunately, I don't know how to proceed. Some help would be appreciated.

The print_exception method will only work when there is an exception to print, i.e. within an except: block.

i.e. something like this:

try:
    some_function("foo")
except:
    console.print_exception(show_locals=True)
