I have submitted many times,but I received "Compilation Error"as the same.
Here is the details of the CE:
""Can\u0027t compile file:Compilation process returned error: execution failed because of unknown invocation error"
Can someone give an explanation,please? Thanks very much.

There is a problem with your invocation.
Now it can be submitted and I got an "AC" successfully.Thanks a lot!
