LR Classic 7.5 Sync error "bad argument #1 to '?' (number expected, got nil)

I have trouble syncing LR Classic 7.5 with the ipad app and Lightroom CC. 21 pictures are marked with a sync error (the sync arrow with the three dot below) and trying to re-sync doesn't work. The sync information appearing in blue on the upper left shows "syncing 32 photos" but there is no progress whatsoever, and the synchronization of new photos doesn't happen. I have tried deleting the sync.lrdata file several times, and even reinstalled LR Classics, but nothing seems to work.

I'm on a mac sing High Sierra 10.13.6

Any idea how to solve this problem?

Thank you for the hints. I had to downgrade to 7.3 and finally it worked again.
Thank you Adobe, you just stole 3 hours of my life.

If you are still having trouble even after updating to 8.0, you might want to try the solution that worked for me:

I had downgraded to 7.4 to help with stuck images, which worked for the most part. I did however still have another problem. There were many images that were not able to sync and had a status of Pending, apparently because they were deleted outside Lightroom (I believe). In the Lightroom Sync page, in the list of pending items, there's the gallery and asset in the Asset Path/Link column, and in the Sync Details/Errors column were the filenames. I verified that the images were missing on the local computer, but I couldn't tell if they existed in the online album because there's no way to see the original filename of the images, that I'm aware of, and I just didn't know what the images were to be able to verify by sight. I went ahead and upgraded to 8 to see if that helped, which it didn't. I finally decided to perform the Delete All Synced Data option while still on version 8. That worked, and all the pending / missing files were gone from the synced activity, and after a several hours the online albums were rebuilt and the collections were synced to my phone.

Is it correct - the Upgrade to 8.0 for LR Classic CC worked for you after you klick to delete all Sync Data ?

It worked for my problem, which had to do with the deleted images. I forgot to add that I also noticed that there was a tool-tip when I hovered over an error giving suggestions for that entry. Another thing I noticed was that after the refresh was done I had a few images with the error "Master Record Missing". When I double-clicked on the error it went right to the photo in question so I could deal with it. I'm not sure if that was in 7.4 / 7.5. I was able to resolve the errors and all was well. Again, this was while running 8.0.

The upgrade to Lr Classic 8 made things worse -- now I have 70 photos syncing and no information about which photos or why they're stuck. So frustrating.

I am sorry to hear that, but thanks for sharing. I will wait to read here that LR Classic 8.X fixes the issue before updating.

A downgrade to LR Classic CC to 7.4 helped me solved the sync problem on my Mac. Is anybody from Adobe here ? That´s not good news for us that V 8.0 from LR Classic CC doesˋnt solve our sync problem. Is the problem in work by Adobe ???

I think I must disappoint a lot of you. I just updated to the new version 7.6 and I still have the problem. My sync has halted completely.

You mean Lightroom Classic CC 8.0 i think. If not, try this new version.

Yes, sorry. Release 8.0 - I just wonder how they justify that jump. I really don't see any big new features or design.

I am running macOS 10.13.3 (17D102) and LR 7.5. I get the same message all the time "bad argument #1 to '?' (number expected, got nil)"

Also, when I edit information, such as ratings and flags on iOS that information is not synced back to LR Classic.

As today, is downgrading still the only solution?

See the first answer by Sahil.Chawla This helped me, but I don’t have a large amount of photos to sync, a few hundred.

First off: Sorry if this is I've posted in this in the wrong position.

Regardless - Regarding the Sync errors between LR CC and LR CC Classic - reverting LR CC Classic to Version 7.4 (from 7.5) seems to have fixed the 'hung' sync issue (mine was stuck at 23 photos), and as well as the 'missing argument' issue.

Changes made to photos this morning on my Macbook (LR CC) that did not sync to the my Mac (LR Classic) all showed up once I rolled LR CC Classic back to V. 7.4.

At this point I think I'll wait for 7.6 to show up and see if that is more reliable with respect to syncing between devices.

Hope that helps

I have the same problem. It is very annoying. Hopefully this bug will be fixed soon.

Also I am tired of having to log in to CC after each restart of my computer.

I also have this problem. Following suggestions on this thread, I downgraded to Lightroom Classic CC 7.4 and within minutes all sync activity is cleared. I spent ages trying to fix this - deleted photos, reimported them, etc., etc., all to no avail. Wish I had seen this thread earlier. Thank you the contributors.

I have the same issue in LR 7.5.

Initially a small number of upload errors appeared to be blocking syncing of 263 photos. Followed the CMD-ALT command in preferences to rebuild the data. This simply increased the number of upload errors to around 100, but did not unblock the process.

Downgraded to version 7.4 and all upload errors disappeared, but the syncing with 263 pictures from my iPad still appears blocked. IPad shows that it is fully synced and up to date.

I do have most of my images on a NAS, with the catalog on an SSD. However, as far as the original post topic of the error message, It only affected a few of my .jpg images. After I ran the "Rebuild Sync Data" option the error entries went away, however I still have an issue that I think I know the answer to. After all updates are done, I still have "Syncing 669 photos", and they are all pending, however they also seem to be missing files from the Windows PC. I refuse to do anything more drastic, because what I want to sync is working fine. So if there's a way to clear this out other than what I've already done it would be great.
