Syncing errors

[wildglio]

The synching activity window shows I have many files with an error stopping the synching. The error for all of them is "bad argument #1 to '?' (number expected, got nil)" What does this mean? The file name for the first error is WS1_Index1.dng I cannot see that there is a problem with the file name.

Hi wildglio,

Sorry that you're getting an error message while syncing your images from Lightroom Classic CC.

Could you please try the following? 

In Lightroom Classic CC under the Preferences -> Lightroom Sync menu  Press alt/option -> Rebuild Sync data . Lightroom will restart and syncing will reset and there will be no impact on your images.

You may also refer this discussion for more details:  Lightroom Classic: sync problem: bad argument #1 to '?' (number expected, got nil) | Photoshop Famil...

Let us know if that helps.

Thanks,

Akash

Akash,

Rebuilding Sync data, has made a difference. I now no longer have any files pending, but now have the following

     1 x Sync Type 'downloading' with Sync details/Errors 'Allow file to sync from my iPad'

     3 x Sync Type 'Error' with Sync details/Errors 'bad argument #1 to '?' (number expected, got nil)'

     4,718 x Sync Type 'Uploading' with Sync details/Errors shown as 'Error' and 'bad argument #1 to '?' etc.

The page shows a total of 7773 photos synced

I have generated a diagnostic log, but will not post it here as it includes sensitive data.

What can I do now?
