Error creating sidecar files

[ljwolfe]

Hopefully this is the right place to ask :-). I'm new here, please go easy on me.

I'm in the process of downloading an 80K+, multi-level-folder archive, and have been having trouble with downloads randomly failing on creating sidecar files.

It looks like #1063 (comment) is a solution, but I'm not sure how to implement the fix. It's been months since I set this up so I forget all the steps I took at the time, but now I just run the batch file and it works.

My programming chops are decades out of date, so there are some things I understand quickly and others that feel like I'm trying to understand Martian, so please explain it to me like I'm five :-).

The errors go something like this:

H:\iCloud photos>cmd /k icloudpd --username {username} --directory downloads --folder-structure none --size adjusted --size original --set-exif-datetime --keep-unicode-in-filenames --live-photo-mov-filename-policy original --file-match-policy name-id7 --align-raw original --xmp-sidecar --album "temp 4 download" --only-print-filenames
downloads\IMG_1612-adjusted.JPG
Traceback (most recent call last):

File "icloudpd\xmp_sidecar.py", line 71, in generate_xmp_file
File "icloudpd\xmp_sidecar.py", line 108, in build_metadata

Then the next part varies. Some examples are:
zlib.error: Error -3 while decompressing data: invalid distance too far back
[PYI-24156:ERROR] Failed to execute script 'icloudpd' due to unhandled exception!

zlib.error: Error -3 while decompressing data: invalid code lengths set

zlib.error: Error -3 while decompressing data: invalid block type
[PYI-20200:ERROR] Failed to execute script 'icloudpd' due to unhandled exception!

I haven't been able to identify anything the failing images have in common except maybe "-adjusted." Sometimes a group of photos from the same camera and date are fine, other times it'll fail after a few images, or on every one of a group.

Thanks!
