Data loss in Photos Service about duplicated RecordName

[landall]

• pyiCloud release with the issue (pip show pyicloud): 1.0.0
• Last working pyiCloud release (if known):
• Service causing this issue: photos
• Python version (python -V): 3.10.11
• Operating environment (project deps/Docker/Windows/etc.): Windows

I find a case of data loss when I fetch my icloud photos.

There are 77864 items in All Photos Album. (len(api.photos.albums[album]) = 77864)

	for photo in api.photos.albums[album]:
		print(photo.id, photo.filename)
		list.append({'id': photo.id, 'filename': photo.filename, 'added_date':photo.added_date.strftime("%Y-%m-%d %H:%M:%S") , 'master': photo._master_record, 'asset': photo._asset_record})
	with open(filename, 'w') as f:
		json.dump(list, f, indent=4)

There are only 77863 items in the saved json file.

more than 700 items have duplicated RecordName but only 1 items is lost.
I run the code serveral times and lose the same item.
No file is added to the icloud photo when I run the code.

The website of icloud.com.cn shows two items of this RecordName, so this is a issue of pyicloud or my code.
but I don't find where is wrong.

I print out the response.json in the source code of PhotoAlbum.photos.
Only one item is returned from the server.
Maybe it is some issue about the request params.

some log I print out for each response from the server.
The 3 numbers in the second line are {counter of CPLMaster, count of the response json, count of CPLMaster in the response json}
offset= 0
100 200 100
offset= 100
199 199 99 (this line means 99 CPLMaster and 100 CPLAsset in the response json)
offset= 199
298 199 99
offset= 298
398 200 100
offset= 398
498 200 100
......
offset= 77686
77784 199 98
offset= 77784
77864 162 80
offset= 77864
77866 4 2
