Post request to API returns Response code 500 (Internal Server Error)

• Node.js version: 16.20.2
• OS & version: Rocky Linux 8.9 (Redhat)

I have an API written in C# .NET. One of the endpoints allows users to unsubscribe from emails and does not return any json response.

When using CURL or Postman, the API returns a 200 status code. GOT returns a 500 server error. On the web server itself, I see the following in logs:

Line 105662: 2024-02-15 09:26:14 10.52.1.9 POST /Tapier/api/TapierSubsciption/Subscribe isUnsubscribe=true&email_id=someemailid&healthcheck=1 443 - 10.52.1.211 got+(https://github.com/sindresorhus/got) - 500 0 0 307
Line 200535: 2024-02-15 16:40:19 10.52.1.9 POST /Tapier/api/TapierSubsciption/Subscribe isUnsubscribe=true&email_id=someemailid&healthcheck=1 443 - 10.52.1.211 PostmanRuntime/7.36.1 - 200 0 0 985

I am unable to upgrade to a more recent version of nodejs as the host is outside of our control.

I can confirm the issue also occurs on Nodejs 18 and Nodejs 20 in [email protected].

Actual behavior

The following error is reported after running the script:

HTTPError: Response code 500 (Internal Server Error)
    at Request.<anonymous> (file:///home/vagrant/samplenodejs/node_modules/got/dist/source/as-promise/index.js:86:42)
    at Object.onceWrapper (node:events:628:26)
    at Request.emit (node:events:525:35)
    at Request._onResponseBase (file:///home/vagrant/samplenodejs/node_modules/got/dist/source/core/index.js:604:22)

    at async Request._onResponse (file:///home/vagrant/samplenodejs/node_modules/got/dist/source/core/index.js:646:13) {
  input: undefined

Expected behavior

Curl and Postman both return 200 status codes. Expecting the same from GOT.

Code to reproduce

The API endpoint in the sample is an non-working example but the rest of the code is valid.

import got from 'got';

const url = 'https://api.domain.my/TapierService/api/TapierSubsciption/Subscribe?isUnsubscribe=true&email_id=someemailid&healthcheck=1';

const options = {
        body: '[{"subscription_url": "","event": ""}]',
        headers: {
          'Content-Type': 'application/json'
        },
};

const data = await got.post(url, options);
