P: Error while creating Virtual Copies

[A2Z101]

When I try to create a virtual copy in Lightroom ClassicI get the following error:

"An internal error has occurred. ?:0: attempt to index field 'additionalDevelopMetadata' (a nil value)".

The error started after I combined a second catalogue into a main catalogue using the 'Import from another catalogue' function.

The error only happens with the images from the second catalogue that have been imported into the main catalogue. All other images in the main catalogue are fine. I still have the second catalogue and the virtual copy works correctly in that catalogue as well, so the issue appears to be related to the import process. The reason for combining the two catalogues was to reduce the need to swap between the two.

I had already done quite a bit of work on the imported images before I came across the virtual copy error, so I now have a bunch of edited images in my main catalogue that won't allow VCs to be created, and a bunch of un-edited images in the old second catalogue that will allow VCs to be created.

My system details are as follows:

I am running into the same problem.  I just installed Lightroom Classic on a new computer and imported the catalog from my old machine.  I don't know if it is relevant, but my old machine was running Windows 7 and had an older version of Classic running on it.

Thank you for your patience.

I've just tested this and it seems to work - thank you!

I am not seeing the update.  My system says it has version 9.1 and that it is the most recent.

My version is 9.2, build 202001311240-2d026470.

It took a while to show up, but I've now been able to upgrade to 9.2 and everything works fine.
