Lightroom Classic CC stuck syncing 1 photo, have tried Rebuild Sync Data

For months my Lightroom Classic CC desktop has been stuck syncing 1 photo, but I didn't bother troubleshooting. I recently uploaded a lot of content to Lightroom mobile while I was away for some weeks, when I got home it was now stuck syncing a couple hundred photos. I tried the "Rebuild Sync Data" suggested in some forums, and it cleared away the couple hundred photos, save and except for one single photo (the same offending one or a different one, not sure). I have tried "Rebuild Sync Data" multiple times (and, of course, restarting my system entirely), but still it remains stuck syncing one photo... help?

OS 10.13.6 // Lightroom Classic CC 7.5

Correct answer john beardsworth

hum, seems to be quite a mess. At this point, not sure how to identify the offending photo, as there seem to be thousands of sync errors overall... At least Web and Mobile seem to have the same number for "all photos"

see details below, help???

Lightroom Classic CC desktop >> 21,418 synced photos + 4,257 sync errors

Lightroom mobile on my iPhone >> 25942 photos

Lightoom Web >> 25942 photos + 234 sync errors


But this is a wholly-different order of magnitude than your initial post. I don't think you're going to solve it as easily as with one problem image, and I am probably going to recommend the Preferences / LRCC / Delete All Data route, but let's proceed slowly - don't zap the mobile data yet.

Your synced images. Where exactly do they originate? Are all of them images that you have synced from Classic? If that is the case, you could use Delete All Data and resync them. But it's more likely that the synced images are a mix of stuff synced from Classic, and stuff imported into LRCC. So before we zap the mobile data, please say where the synced images originate. Are many of them iPhone photos? If so, are they photos taken with LrMobile, or were they taken with the iPhone camera and imported? Have images got into Sync from some other source?

Hi Andrewklug,

Sorry that you have 1 image stuck in the Lightroom(Classic CC 7.5) sync activity menu and doesn't syncs to the cloud despite rebuilding the sync data and deleting many images.

Could you please Log into Lightroom Web (Photo Editor | Online Photoshop Lightroom ) and check if that 1 image still hanging around? If so, delete it and then rebuild the sync data and let us know how it goes.

Thanks,

Akash

Hello Akash

Apologize for any misunderstanding, to clarify, I did not delete any images, I simply rebuilt the sync data and the thing got almost cleared up, but still stuck at "syncing 1 photo"... I don't know if it's the same offending photo, or a different one.

Now it gets even more strange... if I look under Sync Activity in the Preferences window, I see a large number of files uploading and downloading, but one error at the bottom. So I click on that and it brings me to the image, I change the image rating but now it's showing me errors on different files, so it seems like it's just getting worse and I have no idea why these files are giving error, they are files I haven't touched in a long time

Once you get the downloaded content, the key thing is that you have them in your own safe custody (at that point you could go nuke). After that, sorting out what you've downloaded is less critical, though it's likely to be a tedious, common sense process. First you would get them into a new LR catalogue and identify the smart previews - the filename shows that. You can then look at what's left, so let's say you have had a couple of phones. You might see 345 pics from the old one, and 345 are in your main catalogue - so everything made it down. Then on the new phone there might be a difference of 15 photos, maybe dating from the last couple of weeks.

I wouldn't want to eyeball every file, so personally I would first back up the download content, import it into a new catalogue, and use it to delete all the smart previews that were downloaded. Next I'd the import the remaining originals into my main catalogue. Without testing, I am guessing that Import's Do Not Import Duplicates might prove helpful here, allowing me to automate the process of finding the "never made it down" images.

As for the "234 sync errors on Lr Web", I am suggesting that you ignore this item. It's quite new, and in my opinion it's not yet of any value. If anything, it tends to tell you what never made it up. It doesn't do any harm to review what's there, but I doubt it will help you.


Hello again John. Reaching out because a little more than a week after wiping all my synced data and starting with a fresh slate, I am once again experiencing irregularities. Per below screenshot, there are a total of 409 synced images now, ie many orders of magnitude less than previously. About half of those are UPploaded from Lr Classic CC in a Collection that I would like to be able to view on mobile. The other half are iPhone imports that have made their way DOWN into Lr Classic CC from mobile.

As you can see per the below screenshots, there are 11 files that are "pending" even though Lr mobile says sync is "up to date", even after waiting a good while and restarting my iMac several times these images are stuck as pending.

In addition, there is one error "bad argument #1 to '?' (number expected, got nil)"... there were 2 images with this error, both inside the collection that has been uploaded from Lr Classic CC, I managed to get rid of one by re-saving the metadata, but the other error sticks. Very annoying.

Overall, a severe disappointment. It seems that the Lr sync mechanism is anything but robust. I think adobe needs to sort things out once and for all, I am tired of this.
