Parse Error on DELETE request

See original GitHub issue

Current behavior:

My page send a DELETE request with a json body to the server that correctly respond with status 204 and empty body (I verified it both on server logs and using wireshark)

cypress instead show a 500 status in the command log and if I print the response body with

cy.wait('@deleteApn').then(xhr => {
    cy.exec(`echo ${JSON.stringify(xhr.response.body)} > aaa.json`)
})

I get

<!DOCTYPE html>
<html>
<body>
Cypress errored attempting to make an http request to this url:
http://172.17.102.170:3000/nc/api/apn/
The error was:
Parse Error
The stack trace was:

This is likely a bug in Cypress but it’s likely your server doing something funky to cause it.

My guess is that your server is sending back something like: Content-Type: application/json but then sending an empty response body (which is invalid). Cypress should probably handle this instead of dying - but we need to be able to reproduce this in order to fix it.

Can you send us the response exactly from your server - including headers and body. You could export as HAR. Even sending what it looks like when you work outside of Cypress would be enough for us to mimic and likely reproduce.

If what I suspect is the problem it will be easy to fix and we can get a patch out.
