read:ECONNRESET with Axios - axios

Question

I've encountered read:ECONNRESET error while I was trying to some data through axios post.
A configuration for Axios is
const http = require('http');
const https = require('https');
const axios = require('axios').create({
//keepAlive pools and reuses TCP connections, so it's faster
httpAgent: new http.Agent({ keepAlive: true }),
httpsAgent: new https.Agent({ keepAlive: true }),
});
function to send post request is
axios.post(`${HOST}/sendEmail/`, qs.stringify(params))
.then(() => {
if (conversation.managerUnreadCount) {
console.log('[todo] conversation.managerUnreadCount ', conversation.managerUnreadCount);
}
})
.catch((err) => {
console.error('err in axios', err, url);
});
Error is below..

And in my system many different post requests are made at same time.
(not same url with above)
I thought if I added keep-alive options where axios created, but it did not help.
Any other ideas to resolve this error?
Thank you for reading.

Answer 1

I had the same problem. Turns out I was running script from a local machine that had intermittent Internet connection. Fixing the connection solved the issue.

Answer 2

check error log at api side.
In my case, it was error from api side which was throwing exception and its leading to this error.
