Why is axios + express running for a long time?

Question

Express.js

Hello! There is a mobile application that directly accesses the 1c http service within the local network. I wanted to implement the ability to access data via the Internet, but in order to protect 1C, I decided to create an intermediate backend on nodejs, with an API key and authorization. But how now to implement a data request from Node to 1C?
wrote this method:

app.get('/getProducts/:group', async function(req, res) {
   await  axios.get(`http://192.168.1.100/App/hs/market/${req.params.version}`,{
        auth: {
          username: "",
          password: "",
        },
      })
      .then((data) => {
        res.send(data.data)   
      })
  });

but it works very slowly.
Tell me, please. how right?
