i don't know how but thank you for your answer it helps me, i will try another way

map is not used in the tests, it's part of your code, you're trying to use it with null, don't.

i saw this thank you but the error is always here

Description: If the input array is null, return an empty array

Error message: Cannot read property 'map' of null

Please, refer to this page -> https://en.wikipedia.org/wiki/Reading_comprehension
