Course 1 week 3 assignment autograder showing fail but passed all task in notebook

even though I passed the entire assignment of course 1 week 3 autograder is showing a fail. how can I fix this issue?

where are the mistakes? can anyone help me?

The most common way to get that behavior is to reference global variables in your logic. Are you sure you referenced the parameters that are actually passed to get_country and not the global variables that happened to be passed in that one instance of a test?

Thank you so much. It was helpful.
