P: Content Credentials causes exports to skip

Lightroom 15.5. Lightroom Classic and Lightroom is having export failures when trying to export with Content Credentials. Error seen below. 

Everytime I try to export any size of gallery, Lightroom fails and gives me the error of error couldn't apply content credentials, or it just says it cannot export the files. This is getting very frustrating because then I have to go re-export those files, on a 200+ gallery and I have to do it multiple times for one gallery. The wedding gallery i just exported took 15 exports to export 450 images. This is unacceptable and costing me valuable time I could be using on other clients. 

I am getting this error exporting with or without credentials on every batch export. I have to redo exports 3-4 times for them to acutally create all the exported files. On a PC and not MAC but behavior is the same.

I am not sharing my private RAW files. … Export WITH Content Credentials: Fails consistently on the same 14 assets with 'Error 9 (no network access)'.​​​​​​​

That very much sounds like a bug. Unfortunately, unless Adobe can easily reproduce the problem, they’re not likely to pay much attention. So if you’re not willing to provide a sample raw that provokes the problem (along with the rest of the Export settings), the bug will likely go unfixed until someone else provides a reproducible test case.

The engine should not abort the entire file write just because a beta cloud-signature fails.

That’s the way Export is designed, so Adobe wouldn’t consider this a “bug” (under their definition of “bug”). But you could file a feature request here:

The error message is, “Couldn’t apply Content Credentials (no network access) (9)”  Applying Content Credentials during export (via the Content Credentials section of the Export settings window) does indeed require network access to Adobe’s servers.  It’s entirely possible that during export, LR was temporarily unable to contact Adobe’s servers for some reason.

Adobe is unlikely to pay much attention unless they can straightforwardly reproduce the issue.  As first steps:

1. Provide one or more full-resolution screenshots (not phone pics) showing all the settings in the Export settings window.

2. Do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

3. If you rerun the identical export (with the same photos), does the error message occur again?  Does it happen on the same photos or different ones?  If it happens on the identical photos, then select two of them, do the menu command Metadata > Save Metadata To File, and attach the .arws and their .xmp sidecars here.  We can see if exporting them with the same exact settings produces the same error on other LR configurations.

Lightroom Classic silently skips files during batch export if it fails to write Credit/IPTC metadata. Additionally, it misreports local file errors as network issues.

Steps to reproduce:

1. Select a batch of images (e.g., 120 files).

2. Export with a metadata preset that includes Credit/Copyright info.

3. Observe that some files are randomly skipped.

Actual Results:

• Only a portion of the files (e.g., 106 out of 120) are exported without a proper per-file error log.

• A "No network access" error pops up mid-export despite a perfectly stable internet connection.

• The export engine deletes the entire image file if the metadata write operation fails, instead of just skipping the metadata and saving the image.

Expected Results:

• Lightroom should export the image even if metadata injection fails (best-effort export).

• Errors should be accurately reported (local I/O failure, not "No network access").

• A detailed log should show exactly which files failed and why.
