Using this code fixes the problem as Stefan pointed out I had the type of the
exception and not the value of the exception.
if( PyErr_Occurred() )
{
PyObject *type, *value, *trace;
PyErr_Fetch( &type, &value, &trace );
PyObject *u_why = PyObject_Str( value );
PyObject *b_why = PyUnicode_AsEncodedString( u_why, "utf-8", "strict"
);
int size = PyBytes_Size( b_why );
char *why = PyBytes_AsString( b_why );
printf("Error: %*s\n", size, why );
return 0;
}
