This is not an issue but a problem with your code. Issues are problem caused by defects in the kata itself. You'd rather ask a question in this case. However with no more elements, it's impossible to help you. I guess you're using Python. Actually you don't pass all tests, they give up once they meet an error. KeyError means you try to access a key that does not exist in a dictionary or a similar object, and Python crashes in those cases. Hopefully this may help you: Troubleshooting Your Solution.

All my tests are passed but one got terminated because of key error.What to do?

My bad, totally forgot about that. Thanks again! :)

FYI your reference solution is wrong as it doesn't check for case sensitivity issues ~~ I've fixed that in the editor ^^

Thank you!!!

Approved !!!

It's already implied.

Add up the letters (case-insensitive)

You're trying to access non-exist keys, check for spaces.

Nice one xD

JavaScript translation kumited, feel free to check :)

that is probably because your code doesn't work for names which have two words like 'Donald Trump'. you need to figure out a way you can ignore the space('') between the words.
hope this helps. :)

Well all tests pass, but exit code says this

Traceback (most recent call last):
File "main.py", line 49, in
test.assert_equals(sexy_name('DONALD TRUMP'), "THE ULTIMATE SEXIEST")
File "/home/codewarrior/solution.py", line 10, in sexy_name

KeyError: ' '
