Why are the requests not getting through?

Question

JavaScript

Good evening. I have a function to save company data, if I move console.log to the bottom of both functions, nothing appears and there are no errors either, I'm confused .. Please tell me what to do?
1. There is data in req.body
2. Inside the sql query I can get console.log
Front

$(document).on('click','.save',(e) => {

  saveCompany('/save-company')

})

async function saveCompany(url) {
    this.url = url
    this.options = {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        id: cID,
        face: $('.face .value').text(),
        physic: $('.physic .value').text(),
        index: $('.index .value').text(),
        phone: $('.phone .value').text(),
        orgn: $('.orgn .value').text(),
        region: $('.region .value').text(),
        city: $('.city .value').text(),
        street: $('.street .value').text(),
        bank: $('.bank .value').text(),
        bik: $('.bik .value').text(),
        rs: $('.rs .value').text(),
        ks: $('.ks .value').text()
      })
    }

    console.log('func working')

    const response = await fetch(this.url,this.options)
    const data = await response.json()

    if(data) document.location.replace(`${data.page}`)

    

}

Back

app.post('/save-company',async (req,res) => {
  let face = req.body.face,
    physic = req.body.physic,
    indexx = req.body.index,
    phone = req.body.phone,
    orgn = req.body.orgn,
    bank = req.body.bank,
    bik = req.body.bik,
    rs = req.body.rs,
    ks = req.body.ks,
    id = req.body.id,
    region = req.body.region,
    city = req.body.city,
    street = req.body.street

  await pool.query(`UPDATE the_company SET ? WHERE id = '${id}'`,{face,physic,indexx,phone,orgn,bank,bik,rs,ks,region,city,street}, (error,results,fields) => {
    if(error) console.log(error)

    console.log('ok')
  })

  console.log(req.body)

  return res.send({page: '/control-company'})
})

I suspect due to format mixing. Usually you need to use either a callback or a promise, and not all together, as you have.
