Can't find error...
When ever there is a local challenge, I work trough all the steps and finish the challenge. In my IntelliJ my code runs exactly how it's supposed to be. But when I upload the submission zip I always get "Oh no! We encountered an error with your last submission" after checking the code. I really don't know what's wrong or which changes I should make... Can someone please help me?
Edit: I ran the tests locally and they all passed. So I showed my code to a senior java developer. He says he can't find any errors to. So he thinks maybe it could be a problem with different versions. Because there are no more details in the error message it's really difficult to understand what the problem is.... Could it be a problem with different versions of idk IntelliJ maybe?
