Thanks for message. I was just testing it. Yes the did not implement the 
`__pairs` method for job_desc in job_submit_lua.c

```

static void _push_job_desc(job_desc_msg_t *job_desc)
{
     lua_newtable(L);

     lua_newtable(L);
     lua_pushcfunction(L, _get_job_req_field_index);
     lua_setfield(L, -2, "__index");
     lua_pushcfunction(L, _set_job_req_field); 
 

     lua_setfield(L, -2, "__newindex");
     /* Store the job descriptor in the metatable, so the index
      * function knows which struct it's getting data for.
      */
     lua_pushlightuserdata(L, job_desc);
     lua_setfield(L, -2, "_job_desc");
     lua_setmetatable(L, -2);
}

```
