Solve the following python programming problem given the following code:
@ with_setup (setup = cleanup) 
def test_call_api_before_reply() : 
    def setup_cb() : 
        cmd = ('let g:result = rpcrequest(%d, "client-call2", 1, 2, 3)' % cid) 
        vim.command (cmd) 
        eq (vim.vars ['result'], [7, 8, 9]) 
        vim.stop_loop () 
def request_cb(name, args) : 
        vim.command ('let g:result2 = [7, 8, 9]') 
        return vim.vars ['result2'] 
vim.run_loop (setup_cb, None, setup_cb) 

    
    

    Fix the buggy line: vim.run_loop (setup_cb, None, setup_cb)
