P: CEP regressions in Photoshop 2022 (v23.x) - Windows

Hello.
 
I have been testing my CEP extension with the latest version of Photoshop (and other CC apps), and I am encountering regressions in the CEP system.  For clarity, I am reporting only one issue per post.
 
ISSUE:
XMLHTTPRequest fails with CEP console reporting: "DOMException: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'https://[server].com/mx/versioning/rcsinfo': Document is already detached."
 
Platform: WINDOWS 
 
Severity: As you would expect, this is a critical issue.  It renders my CEP extension completely unable to perform its duties, as it is not able to communicate with our server.
 
This issue is present in Photoshop v23.1 (Windows only - the macOS version works), but it is not a problem in Photoshop v22.5.4.
 
Illustrator v25.4.1 (Windows) also presents this issue.

Hi 

I have encoutered this issue too, and after some digging I found a solution to it. 

The problem shows when you have an iframe in your panel, and send a xhr request after removing the iframe, the error shows up "Document is already detached." 

the key is adding  --mixed-context parameter to your manifest, as below

     <Resources>
                    <MainPath>./index.html</MainPath>
                    <ScriptPath>./jsx/init.jsx</ScriptPath>
                    <CEFCommandLine>
                        <Parameter>--enable-nodejs</Parameter>
                        <Parameter>--mixed-context</Parameter>
                    </CEFCommandLine>
                </Resources>

 

then you will find everything goes well.

    Thanks, Jeffery.

     

    I've been studying the failure some more, and I believe it might be tied to the way <iframe> elements are handled in the newest CEP implementations.  We use an <iframe> to present our UI, and it communicates the user's intended action to our extension's bundled code via browser messages.  When that happens, the bundled code will often rely on XMLHTTPRequest to acquire data from the server, and that's when the "Document is already detached" error rears its head.

    Thanks. I've asked engineering to take a look.
