BUG: AI tagging hangs indefinitely when an image fails to load, blocking subsequent tagging jobs

[Prince-ES]

Is there an existing issue for this?

• I have searched the existing issues

What happened?

Description

While AI tagging, if the backend encounters an image that it cannot load (cv2.imread() returns None), the entire AI-tagging job stops instead of skipping the image. The folder remains in the "processing" state indefinitely, and any following queued folder also remain pending until the ai tagging process of the folder that has problematic image, is turned off. Still we need to restart the subsequent folder's ai tagging.

What backend logs:-

Failed to load image: -path-
Error processing untagged images: object of type 'NoneType' has no len()

problematic image:-

properties: -
format: JPEG
resolution: 616 x 920
size: 79kb

Current behavior

Expected behavior

• If an image cannot be loaded, log the error.
• Skip the problematic image.
• Continue processing the remaining images.
• Continue processing later queued folders.

@Prince-ES can you give me a test image so i can download and check it , because it looks good on my end.??

backend image:

On my machine the original file consistently reproduces the issue. Re-saving the image in Paint as a new JPEG makes the problem disappear, so even though the visual content is identical, the file itself changes and AI tagging succeeds

let me know if this works btw

Regardless of whether this exact image reproduces, I think the underlying issue is that the backend assumes every image loads successfully. If cv2.imread() returns None for any image (corrupted file, unsupported encoding, etc.), AI tagging should skip that image and continue processing instead of leaving the entire queue stuck

i see what you are trying to say. I cannot reproduce this issue on my system its fine. But i think if this issue is there, then yes we can add error handling for this.
Let's see what rohan has to say.
