老师，请问下我在excel表中添加了依赖字段的数据后，进行运行代码就会报错，提示：IndexError：列表索引超出范围。。。。如果不添加依赖字段，接口就可以正常运行，你帮忙看看什么原因，下面是我的代码和截图

class RunMain:
def run_case(self):
rows = excel_data.get_row()
for i in range(rows):
cookie = None
depend_data = None
data = excel_data.get_row_value(i+2)
is_run = data[2]
is_depend = data[3]
param = data[7]
if is_run == ‘yes’:
if is_depend:
depend_key = data[4]
depend_data = get_data(is_depend)
param[depend_key] = depend_data

            method = data[6]
            url = data[5]
            excepect_method = data[11]
            excepect_result = data[12]
            head = data[8]
            if head == 'yes':
                head = get_header()
            res = request.run_main(method=method,url=url,data=param,header=head,cookie=cookie)
            print(res)


            code = res['state']
            message = res['success']
            message = str(message)
            code = res['state']
            message = res['success']
            message = str(message)

                config_message = handle_result(url, "state")
                config_message1 = handle_result(url, "success")
                if code == config_message and message == config_message1:
                    excel_data.excel_write_data(i + 2, 14, "通过")
                else:
                    excel_data.excel_write_data(i + 2, 14, "失败")
                    excel_data.excel_write_data(i + 2, 15, json.dumps(res))

                    excel_data.excel_write_data(i + 2, 15, json.dumps(res))

                if code == "1":
                    get_result = get_result_json(url, "data")
                    reslut = handle_result_json(res["data"], get_result)
