Error Checking Certification Practical Exam

Hi all,

After successfully passed Online Quiz, and uploading my Practical Exam packed in .zip archive this is the feedback I got:

Note that this is my second attempt. (Same thing happened for my first try)
UiPath Support team told me that there is no available developers at the moment to check my work so they advise me to post mu issue here.

Please let me know if you had the same problem with Practical Exam for Certification and how did you solved that.
