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.

[COBill]

Revert to V9.4 until Adobe releases a fix.

I am experiencing the same issue on a Windows 10 PC. I have tried optimising the catalogue which is set to sort by capture time.

[carlm7529305]

I am having the same issue on my Mac. I optimized the catalog and checked the sort order and the B is still not working. I also can't drag my images into the quick collection.

[katyt62201717]

For me it’s working now but only when I have the quick collection sorted to capture time

[carlm7529305]

I just changed the sort order on the quick collection to capture time and that did work.

Thanks

I have had this problem repeatedly. The suggested workarounds don't work. I have found that I can get over the problem by creating a new collection, copying all the images in the faulty collection into the new one, and then you can add to it.

I've been working on quite a big book for Blurb in the Book module. I've had quite a few crashes, especially when I try to move from the Book module to Develop. Again, very delaying and annoying.

This is just too bad. I used to love Lightroom and recommend it heartily to all my photo friends.

[Christopher M. Priebe]

@KateW   I've had this problem and it was recommended to go to View>Sort and check "Capture Time".  I did this and it resolved my problem putting images into Collections.  The original instructions are on this thread.  Thanks to member.

[kateW3]

Thank you! Mine are all in 'Capture time' anyway. I've tried changing to Custom or something else and then back to Capture time - makes no difference.. A problem may be that a lot of them are imported from phone pictures sent to me, and have lost capture time and other metadata

[johnrellis]

"A problem may be that a lot of them are imported from phone pictures sent to me, and have lost capture time and other metadata"

Try Sort: File Name instead -- perhaps that will work for you.

[kayesaces]

Though very slow, everything else seems to be working, though if I try to make a quick collection in any way, it says an internal error has occured.

[FeedbackCommunityMember]

A work around. If you make a selection and then hover over the destination collection folder, right click and Add selected photo to this collection. It works for me after I get this error.

[Rikk Flohr: Photography]

Try resetting the preference file: 

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences.

Reset Procedure:

1. Close Lightroom.

2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.

3. Overwrite the Preferences when prompted by the dialog.

4. Close Lightroom.

5. Restart Lightroom.

Does the behavior continue after resetting the preferences?

[FeedbackCommunityMember]

I get this error (An internal error has occurred: ?:0 : Attempt to compare string with nil) in the Develop Module (after completing edits using a preset) when moving from one image to the next in the "film strip"

[catherine_down]

This issue has just happened to me now. I was using quick selection fine at 13:30 today and now 20:15 it's bringing up this error.

I have made no update today.

Any suggestion on a fix?

Did you try this one, recently posted: "A work around. If you make a selection and then hover over the destination collection folder, right click and Add selected photo to this collection. It works for me after I get this error."

I've not. I will pick this up again in the morning and see how it goes. Thank you for your help

I have also recently installed LrC 10 on my PC and found that when I went to add images to a target collection or just drag and drop into a collection, I get the following message, An internal error has occurred: ?:0: attempt to compare two nil values. This is really frustrating me as I'm not a computer buff and therefore I thank you for any help. I understand from earlier post that Adobe are aware of this issue and working on a fix?

[gadgetgeek2000]

I have just upgraded my Lightroom Classic catalog to version 10. I synchronized my library folders and added a new batch of photos. Corrected the metadata, and [CTRL] S to save that back to the files.

Next, I created a Collection to hold these new photos and attempted to add some pictures into this collection. Lightroom won't allow me to add, and is prompting:  [Error] An internal error has occurred: ?:0: attempt to compare nil with string. [OK]
