I do Advanced Certification the answer is miss file or user what’s wrong ,why?
I’m sorry I don’t understand, please tell more detail.
are u referring file/folder out side your project folder?. where have to stored your credentials? . the message says some file is missing and they are not able to evaluate your solution. try to keep use id and password in config file itself.
It also happens if the .Zip file is not uploaded proprely, please ensure it is uploaded correctly.
