Unhandled exception in migrate-google-takeout

[hindsholm]

Describe the bug

I have made a Google takeout and placed the photos and .json files on a drive which is mounted as "external storage" at /MntPhotos in Nextcloud.
All photos have been scanned and are visible in the Memories app.
Now I want to use the metadata in the Google .json files, so I run:

sudo docker exec --user www-data -it nextcloud-aio-nextcloud php occ memories:migrate-google-takeout --override --user=morten --folder=/MntPhotos/Bratten

The command starts scanning but fails on the first file with an unhandled exception.

I have tried different combinations of the --user and --folder options, but I get the same error.

To Reproduce
I don't know what to say here, but the bug is easily reproducable on my setup. The command fails consistently.

Screenshots
Output:

sudo docker exec --user www-data -it nextcloud-aio-nextcloud php occ memories:migrate-google-takeout --override --user=morten --folder=/MntPhotos/Bratten
This command will migrate JSON metadata from Google Takeout to EXIF metadata.
Only metadata that is missing from EXIF will be migrated, unless --override is specified.
It will also update the JSON files to mark them as migrated.
Make sure you have a backup of your originals before running this command.
Also make sure exiftool is working beforehand by running memories:index on some files.
Are you sure you want to continue? (y/N): y

This is a bug in Nextcloud, not Memories

If you want a temporary workaround, you can chagne line 280 of MigrateGoogleTakeout.php to catch \Throwable instead of \Exception. It will still show some errors but continue to the next file.

Do you have a reference to the bug in Nextcloud?

[pulsejet]

No I've no idea. But looking at the trace it seems to be in a hook in the files versions app.
