P: Lightroom Classic: no longer syncs completely, successfully.

Hi,

I am not able to access the above shared link. Can you please re share the files. Thanks.

@jens_koopmann Hey Jens, I just wanted to offer my sincere thanks again for identifying the recent problems with LR sync. I actually managed to finally narrow it down to a series of shots I had taken from 1999-2004 with a Sigma 600mm f/8 mirror lens that does not report its EXIF data. All of these images had been successfully synced before, so it's all really weird. Strangely though, (as nothing seems to be normal with this bug) one single image of the bunch does still sync! Weird.

Thanks again, fellow LR sync sufferer!

Rikk –

Thanks for your patience. I went through the 1,200 or so files in my current portfolio that were synced from LR Classic to the cloud, pulled out the ones that had the metadata "Unknown Lens" and then added them back to the sync one at a time until I found the problem files. I've included those files, their XMP sidecar data, and a screenshot of the shots themselves.

A few things to note: Firstly, all the shots that will not sync (and do clog the sync pipeline, preventing any other files from syncing) were taken with the same camera (Canon D60) and same lens, a Sigma 600mm f/8 mirror that apparently doesn't report any data via EXIF. Secondly, all of these shots have been successfully synced in the past (until about July this year) Lastly, one of the files –the one with the huge silver tank and steam– does indeed still sync, despite having the same "Unknown Lens" metadata criteria (and the fact that it was taken in January 2004 in Iceland just like all the other files) At first I thought it might be that because unlike the other files, I had processed it with Photoshop, and maybe some of the offending metadata got stripped. But when I uploaded the original raw file, it synced just fine too.

Weird.

Let me know if this helps please. Jens & I both look forward to a speedy solution.

Well it is a good start, that you could reproduce the behaviour.

Let's hope now there will be a fix for this soon.

Thank you for the file. I have a Lightroom Classic Catalog with 37000 images synced - no errors

I have added this single image to the catalog and set it to sync.  Image does not sync.

Clearing the image from Synced Collection and All Synced Photos allows Sync to proceed normally and completes.

I will log a bug with the Classic team and include the image you sent.  Thanks for sticking with this and providing the test file. 

@Rikk  Here is one file including the sidecar as an example.

All files failing to upload have the same camera, same file-format (ORF) and same lens (manual Laowa 7.5mm).

Hi Rikk -

I'm not sure yet. All I did was filter for the metadata of "no lens profile", move those files out of the synced collections, and then turned syncing back on, and then suddenly everything worked. 

I think I'd have to add one of the suspect files at a time and see when LR Sync gets stuck. I have to say I **AM** a bit hesitant to do this because I'm afraid of having to start all over again!  😃

Give me a few days to work on this, and then I'll let you know. I'm certainly willing to help quash this bug though!

Your and Jens' reports regarding the unknown lens metadata failing sync is very interesting. 

Do either @hans_rupert  or @jens_koopmann  have a file that that can share with me for testing?

Well, “solved” would be a stretch. LR Sync is still broken; whereas before this July, it was working perfectly.

No, I didn’t actually have to remove all the iPhone photos. In fact, over 100 of them, from iPhone 4s to 5 to SE to XR to XS synced just fine.

As a way to test my progress with things on LR Classic on the desktop, yes I did delete the photos on LR Web, and LR Mobile devices first.

Hi, Hans,

Glad to hear your problem is solved. Do you have to removed the phone photos from your LR CC collections created from the day 1? Do you have to remove photos sync'd from your LR mobile?

Thanks.
