[Bug]: Generated images do not show (403) after latest git pull

[jhlchu]

Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

Updated from d11c9d7 to 3cdae09 to get v-pred on 1.5 working. I updated running

git remote add forge https://github.com/lllyasviel/stable-diffusion-webui-forge
git branch lllyasviel/main
git checkout lllyasviel/main
git fetch forge
git branch -u forge/main
git pull

When I generate an image, the previews show the "missing image" icon in browser. This did not occur prior to updating.
In dev console, it shows Failed to load resource: the server responded with a status of 403 (Forbidden). Following the error, {"detail":"File not allowed: P:/Computing/AI/Stable Diffusion/outputs/txt2img-images/2024-02-12/00028-1799655419.png."} json is returned. Entering the direct path into URL returns the correct image.
The images are being generated and show up correctly in file explorer, they only fail to show up in the interface.

I have narrowed it down to the folder junction. Somewhere between d11c9d7 to 3cdae09 something was added (possibly for security) that is preventing web-ui from accessing the folder junction. My output folder for web-ui is a folder junction to another folder (same drive) where I keep images from all the different interfaces.

When I change the output folder to something that is in the same root path as web-ui, images show up correctly. Changing back to the folder junction breaks it again.

Oddly, it is still able to access other folder junctions like checkpoint and lora.

Steps to reproduce the problem

1. Pull latest.
2. Create folder junction linking output in web-ui to another folder on the same driver but not within the web-ui directory.
3. Generate an image.

What should have happened?

The preview image should of showed up like prior to updating.

What browsers do you use to access the UI ?

Brave

Try adding the path via the command-line argument --gradio-allowed-path.

Are you using a junction to specify the image save path by using "mklink" ? I encountered the same problem as yours when using junction. After I deleted the junctions and specified the image save directory in the settings instead, the problem was solved. It seems that the current forge version conflicts with junction in Windows.

[jhlchu]

Yes. I'm using mklink /J for junctions. @catboxanon 's solution worked for me.
