cross-origin-read-blocking

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 always empty. When I look in Fiddler I get an answer from the server. I try with JQuery, and I also try with an xmlhttp call. Always the same result Did new CORS policy rules apply...? There is my xmlHTTP call var xmlhttp = new XMLHttpRequest(); // new HttpRequest instance var theUrl = "URL"; xmlhttp.open("POST", theUrl); xmlhttp.setRequestHeader("Content-Type", "application/json;charset=UTF-8"); xmlhttp.send('{ "args" :{ "Obj":"my obj"

I am developing a Chrome extension which makes requests from certain websites to an API I control. Until Chrome 73, the extension worked correctly. After upgrading to Chrome 73, I started getting the following error: Cross-Origin Read Blocking (CORB) blocked cross origin response http://localhost:3000/api/users/1 with MIME type application/json According to Chrome's documentation on CORB , CORB will block the response of a request if all of the following are true: The resource is a "data resource". Specifically, the content type is HTML, XML, JSON The server responds with an X-Content-Type

I have called third party API using Jquery AJAX. I am getting following error in console: Cross-Origin Read Blocking (CORB) blocked cross-origin response MY URL with MIME type application/json. See https://www.chromestatus.com/feature/5629709824032768 for more details. I have used following code for Ajax call : $.ajax({ type: 'GET', url: My Url, contentType: 'application/json', dataType:'jsonp', responseType:'application/json', xhrFields: { withCredentials: false }, headers: { 'Access-Control-Allow-Credentials' : true, 'Access-Control-Allow-Origin':'*', 'Access-Control-Allow-Methods':'GET',
