Ajax call bug with Chrome new version 73.0.3683.75?

Question

My code was working fine before the Chrome update.

I make an ajax call to my server. My server receives the call, returns JSON to the client, but the answer is alway

Answer 1

I had the same problem after upgrade to Chrome 73. Thanks to @wOxxOm

This is the workaround until now:

2. Disabled the Enable network service

UPDATE:

This is not a bug, according to this announcement: https://www.chromium.org/Home/chromium-security/extension-content-script-fetches

You will need to put the Cross-Origin Fetches to the background script instead of the content script.
