Select Develop, Open Network, go to a website where you can trigger a POST using AJAX that returns an emptry string for the HTTP response body.
Even when the status is HTTP 200 OK, the Preview window in Orion's dev tools says "An error occurred trying to load the resource" in bright red text.
Here are the response headers:
:status: 200
Content-Length: 0
Content-Type: text/html;charset=UTF-8
Date: Fri, 14 Apr 2023 03:24:49 GMT
Server: nginx
X-Frame-Options: DENY
Expected behavior:
Preview window should be blank. Other browsers displaying the same HTTP response do not show an error message because it is not an error to have an empty body.
Also note that the big red error message was unable to be selected for copy and paste, although that's a side issue.
