I received "Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client"

QUESTION

I received "Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client"

Asked 2020-Dec-15 at 08:00

I used Node.js and Express for the first time to make an API and I am having some issues.
I'm using Node.JS 13.11.0 and Express 4.17.1.
When I try to access 127.0.0.1:4008/api/nbhbdm and append parameters, I receive this error.

I have seen Error: Can't set headers after they are sent to the client, but I don't think I have tried to send multiple responses to the same request.

You have, you just didn't notice it.

The onreadystatechange event is triggered four times (1-4), one time for each change in the readyState.

Source: https://www.w3schools.com/js/js_ajax_http_response.asp

Every time onreadystatechange is triggered and the readyState isn't 4 or the status isn't 200, you try and send a response to the client with res.json(). Since you cannot send several responses to the same request, you get thrown an error.

You'd need your onreadystatechange callback to disregard any readystate that isn't 4, and then act depending on the status of the request:
