Error on line 0 indicating "does not appear to be a unified-diff format patch"

This error has been on my sandbox for the C-Variables project and i have no idea on how to solve it. The checker still checks green on the Betty coding style section but when you prompt Betty to look for error, only this one appears.. Please kindly let me know how it..

re-arrange your header file,
/The initial header file is below*/
#include <stdio.h>
#incude "main.h"
then it shows this error "========== ./1-main ==========
./1-main:0: ERROR: Does not appear to be a unified-diff format patch
total: 1 errors, 0 warnings, 0 lines checked

/but when i re-arrange the header file like this/
#incude "main.h"
#include <stdio.h>
it shows no error again
