Express or Axios Error: socket hang up code: ECONNRESET - node.js

Question

This is the first time i post a question here, sorry if some data is missing.
I'm trying to do some web scraping to get some info of a table.
The page only responds with an index.php and when i use the search form, it makes a POST to index.php?go=le with some formData.
To avoid the CORS problem, im making the post with my own API running in localhost. I'm pointing my frontend to my API and i get the response from localhost.
No problem there.
My problem appears when i try to make a second request to my API. The first GET works fine but after that response it keeps failing.
When i restart the server, it works again but only one time.
Here is my API code. I use nodemon server.js to start my server.
server.js
const express = require("express");
const axios = require("axios");
const scrape = require("scrape-it");
const FormData = require("form-data")
const cors = require("cors")
const app = express();
const PORT = process.env.PORT || 5000;
app.use(cors())
const config = {
headers: {
'Content-type': 'multipart/form-data'
},
}
app.get("/get-projects", async (req,res) => {
const testJSON = await axios.post(baseURL +"/index.php?go=le",formData,config)
.then(res => {
console.log("Post successfull...");
return res
}
)
.catch(err => {
console.log("Server error");
return err
}
);
if(testJSON && testJSON.data){
res.send({status: 200, data: testJSON.data});
}else{
res.status(508).send({status: 508, msg: "Unhandled Server Error", failedResponse: testJSON || "empty"})
}
})
app.listen(PORT,()=>console.log(`App running in port: ${PORT}`))
And in my front-end i only have a button with an event that makes a get to my API (http://localhost:5000)
This is my fetch.js that is included by a script tag. Nothing fancy there.
fetch.js
const btn = document.getElementById("btn-fetch-proyects")
const axios = window.axios
const fetchProjects = async () => {
console.log("Fetching...")
axios.get("http://localhost:5000/get-projects")
.then(res=>
console.log("The server responded with the following data: ",res.data)
)
.catch(err => console.log("Failed with error: ",err)
)
return null
}
btn.addEventListener("click",fetchProjects);
In the console where im running the server, i get Server error with this err object:
{

I hope someone has a clue about what's happening. I tried all day and i couldn't solve it.
I tried posting to other sites, and it works fine. I thing the problem is with the form POST.
Thanks for reading!!!

Answer 1

At a first glance I see an error in your front-end code. You are using async on the function but then you do not await but you use .then, try not mixing up styles, either you use async/await or .then .catch.
Check if that helps! :)

Answer 2

Obviously the socket is hanging!
Use node unirest and it closes the data stream.
var unirest = require('unirest');
var req = unirest('POST', 'localhost:3200/store/artifact/metamodel')
.attach('file', '/home/arsene/DB.ecore')
.field('description', 'We are trying to save the metamodel')
.field('project', '6256d72a81c4b80ccfc1768b')
.end(function (res) {
if (res.error) throw new Error(res.error);
console.log(res.raw_body);
});
Hope this helps!
