P: When trying to add files to Collections I get this error: ?:0: attempt to compare two nil values

[Christopher M. Priebe]

I just installed LrC 10 and when I went to add images to a target collection, I get the following error: ?:0: attempt to compare two nil values.  This is really holding me up organizing my photo book.  Please help.

[garyrowe]

Serves you right for being a beta-tester! 😉

[Christopher M. Priebe]

Yes!  I thought it was simply an update.  Wondering if I can go back to my previous version.

[Bob Somrak]

Works for me on Lr10 and macOS 10.15.7 by using "B" shortcut, Using menu and drag and drop.  

[Sunil_Bhaskaran]

It works for me in Mac and Windows as well?
I am writing you an e-mail offlist to get the catalog.

Thanks,

Sunil

[ragrawal]

What is the sort type selected in the UI ?

[jon_lewis]

Same issue for me, only happened after the update. On a Mac.

[jon_lewis]

Where can I see this?

[Christopher M. Priebe]

I think it may be related to the same image put into different collections under the same collection set. 

[GoldingD]

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

[Stevedocmaker]

I'm having the same issue. Just started suddenly. I tried resetting the preferences, no change.

I tried putting the same images in different collections under the same collection set by changing the "target collection"  to the different collections and it worked fine.  macOS 10.15.7.  I do see a couple of the users having issues are not using 10.15.7 but I can't imagine that would be the issue.

Hi, I recently upgraded my Lightroom Classic and I've lost the ability to add photos to the quick collection (B). It comes up with the following message:

If this bug is happening to you, please also report the current sort order for the collection.  To see the current sort order, select the collection in the Collections panel. Then look in the toolbar at the bottom of grid view or do the menu command View > Sort.

LR 10 made a significant change internally to how the images in a collection are ordered, so more details will help.

[Christopher M. Priebe]

Ok, I just talked to Adobe LcR support and this is a known issue and they are working on a fix which should be available very soon.   If you updated your LRC and Master catalog, you will have to wait for the fix or install the last version of LRC and go back to your previous catalog.  Because I've been working in the new updated catalog for several days, I don't want my work spread over two catalogs so I'll wait for the fix.  If one hasn't updated LRC or your catalog, it's probably better to wait.  IMO.

[FeedbackCommunityMember]

I am also having the same issue with slightly different wording.

"?:0: attempt to compare string with nil"

I can add photos to other collections but not to the one for the book I am working on.

Sort is by "Capture Time"

Ok, I just talked to Adobe LcR support and this is a known issue and they are working on a fix which should be available very soon.   If you updated your LRC and Master catalog, you will have to wait for the fix or install the last version of LRC and go back to your previous catalog.  Because I've been working in the new updated catalog for several days, I don't want my work spread over two catalogs so I'll wait for the fix.  If one hasn't updated LRC or your catalog, it's probably better to wait.  IMO.
