React js async await 函数返回错误

问：

我有一个将数据发送到后端 Node JS 服务器的功能，该服务器获取数据并将其提交到 Postgres 数据库。功能如下handlesSubmitasync

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;
    }
  }

这是我的后端服务器

async postPumpSRPDownAndSurfTrx(req, res) {
    let trx;
    try {
        trx = await db_dwvm.transaction();
        const momentDate = new Date();
        const pumpHeader = {

        }
        const pumpSRPSurface = {

        };
        console.log(pumpHeader)
        console.log(pumpSRPDownhole)
        console.log(pumpSRPSurface);
        const date = new Date();
        const newdate = `${date.toLocaleString('id-ID', { weekday: 'long', day: 'numeric', month: 'long', year: 'numeric' })}` + " Pukul " + ("0" + ` ${date.toLocaleString('id-ID', { hour: 'numeric' })}`).slice(-2) + ':' + ("0" + `${date.toLocaleString('id-ID', { minute: 'numeric' })}`).slice(-2);
        const { username, role, pesan = `Pump Header, Pump SRP Downhole dan Pump SRP Surface Telah Terinput Pada ${newdate}` } = req.body;
        await models.pump_header.create(pumpHeader, { transaction: trx });
        await models.pump_srp_downhole.create(pumpSRPDownhole, { transaction: trx });
        await models.pump_srp_surface.create(pumpSRPSurface, { transaction: trx });
        await notificationvmModel.postNotification(username, role, pesan);
        await trx.commit();
        res.status(201).json({
            message: 'Success',
            error: false
        });
    } catch (error) {
        if (trx) {
            await trx.rollback();
            res.status(500).send({
                message: error.message,
                error: true,
            });
        }
    }
}

我的问题是，当我按下按钮并将数据发送到服务器时，服务器确实会收到数据。但是，即使数据成功提交到数据库，也会以某种方式进入该部分，因此无法正确显示。我认为发生的事情是数据库没有发送到，但已经“获取”了它，它什么也没发现，所以它认为这是一个错误并移动到该部分。我认为是这样，因为在后端终端中，在它从前端接收数据后，它会显示此错误代码submitbackendresponsecatchresponsebackendfrontendresponsecatchconnection closed before res end/flush
