How to solve this “Caution: request is not finished yet in chrome”

by

It is caused by two-step response loading. If you are using some low-level API, make sure that you fetch not only headers, which arrive first, but also body content that comes later as a stream.

I had the same issue when using the fetch function in JavaScript. To solve it, make sure you call a method that reads the body of the response like json() or text():

// Sends request and loads only headers
fetch('/foo');

// Sends request, loads headers and then fetches the body as JSON
fetch('/foo').then(response => response.json());

In my case response headers were also loaded properly and I had a successful HTTP status code, but I was missing the body content and I had Caution: request is not finished yet inside Chrome Developer Tools.
