Is Chrome Debugging Still an Option for Installed UXP Plugins?

Wanted to check if Chrome Debugging is still an option for installed UXP plugins.

I’ve tried debugging and installing a panel with a debug.json

{
  "port": 9981,
  "breakOnStart": false
}

As outlined in this guide:

https://developer.adobe.com/photoshop/uxp/2022/guides/debugging/

But I’m unable to access the port by going to localhost:9981 in the browser or by following the steps in the guide to:

  • Go to chrome://inspect/
  • Configure
  • Adding localhost:9981

Still doesn’t show up after opening Photoshop with my panel, but nothing shows up under targets.

I believe this worked in old versions, especially since it’s in the official docs, so wanted to check if something has changed about this workflow or if it’s been disabled.

Debugging installed panels is really important for troubleshooting issues with builds and on client machines, so having this functionality back is really crucial.

Last time I tried few months back it worked. Does it work with older PS version?

I tested in Photoshop 2023, 2024, and Beta on Windows but it’s not working for me.

It must have worked at one time since it’s in the docs, and I’m pretty sure I got it working a while ago.

Your filename is wrong. It has to be .debug.json

Hmm, tried .debug.json in PS 2023, 2024 & Beta but still not showing up

{
  "port": 9981,
  "breakOnStart": false
}

Did you unload and load plugin again? Or restart PS?

Yea tried uninstalling / installing the CCX. Closing / Reopening the panel. Restarting PS

same too, has anyone successfully tested it?
