"time_machine" code challenge works in my VS Code but not in challenge

Why isn't my code being acccepted in the challenge workspace but will in VS Code?

time_machine.py
import datetime

def time_machine(num, metric):
    starter_loc = starter
    amount_of_time = datetime.timedelta()
    if metric == 'days':
        amount_of_time = datetime.timedelta(days=num)
    elif metric == 'hours':
        amount_of_time = datetime.timedelta(hours=num)
    elif metric == 'minutes':
        amount_of_time = datetime.timedelta(minutes=num)
    elif metric == 'seconds':
        amount_of_time = datetime.timedelta(seconds=num)
    return amount_of_time + starter_loc

starter = datetime.datetime(2015, 10, 21, 16, 29)





# Remember, you can't set "years" on a timedelta!
# Consider a year to be 365 days.

## Example
# time_machine(5, "minutes") => datetime(2015, 10, 21, 16, 34)

The problem with testing in an external REPL is that it has no idea of what the challenge objective is, so it's up to you to perform a comprehensive test which can be more difficult than the challenge itself.

In this case, the challenge instructions say that the function 'takes an integer and a string of "minutes", "hours", "days", or "years"', but the code shown here does not accommodate the case where the argument is "years".
