      Description

      cursor modify operation is failing with the following error.

       requires key be set: Invalid argument
      

      The error is raised from the following call stack.

      #0  __wt_cursor_kv_not_set (cursor=0x555555dcee80, key=true) at ../src/cursor/cur_std.c:201
      #1  0x00007ffff585ff3d in __cursor_checkkey (cursor=0x555555dcee80) at ../src/include/cursor.i:39
      #2  0x00007ffff58679e4 in __cursor_modify (cursor=0x555555dcee80, entries=0x555555dc13d8, nentries=4) at ../src/cursor/cur_std.c:930
      #3  0x00007ffff5bd244a in __wt_cursor__modify (list=<optimized out>, self=0x555555dcee80) at wiredtiger_wrap.c:5428
      #4  _wrap_Cursor_modify (self=<optimized out>, args=<optimized out>) at wiredtiger_wrap.c:5428
      #5  0x0000555555650f6e in PyEval_EvalFrameEx () 
      

      The cursor modify operation is supported for table cursors only where the value format is either 'S' or 'u' for simple tables. During the initialization of the cursor, the default cursor modify function is modified from _wt_cursor_modify_notsup to }}{{cursor_modify. But the }}{{cursor_modify is not designed to operate on WT_CURSOR_TABLE like }}{{_wt_curtable_set_key function, because of this reason it raised the above error.
