我有一个handlesSubmitasync函数来将数据发送到后端Node JS服务器，该服务器接收数据并将其提交到Postgres数据库。

const handleSubmitData = async (event) => {
    event.preventDefault();
    event.target.disabled = true;
    try {
      const body = {
        well_id: well_id,
        date_install_pump: dateform2,
        pump_type: pump_type,
        pump_size: pump_size,
        stroke_length: stroke_length,
        barrel_length: barrel_length,
        gas_anchor: gas_anchor,
        pump_set: pump_set,
        manufacturer: manufacturer,
        installation_remarks: installation_remarks,
        date_install_pu: dateSRP1,
        pumping_unit_type: pumping_unit_type,
        pumping_unit_model: pumping_unit_model,
        motor_hp: motor_hp,
        manufacturer_surf: manufacturer,
        installation_remarks_surf: installation_remarks,
        row_changed_by: users,
        row_created_by: users,
        username: users,
        role: role,
      }
      const response = await axios.post(global.config.i18n.url + 'dw_pump', body);
      if (response && response.data && response.data.message) {
        setIsSuccess(true);
        setModals(response.data.message);
        setOpenModal(true);
      } else {
        setIsSuccess(false);
        setModals('Please check the show all tables page to see your data');
        setOpenModal(true);
      }
    } catch (e) {
      setIsSuccess(false)
      setModals(e.response.data.message)
      setOpenModal(true)
    } finally {
      event.target.disabled = false;
    }
  }

我的问题是，当我按下submit按钮并将数据发送到backend服务器时，服务器确实收到了数据。但即使数据成功提交到数据库，response以某种方式进入了catch部分，因此无法正确显示。我认为发生的情况是数据库没有将response发送到backend，该frontend已经“获取”的response和它发现什么都没有，所以它认为这是一个错误，并移动到catch节.我认为这是因为在后端终端，在它收到数据从前端它显示此错误代码connection closed before res end/flush
