Only 50 images per album with setting folder-as-album: FOLDER

[Wezea]

Hi there,

running an import using this config:

upload:
    admin-api-key: ""
    api-key: ***
    api-trace: false
    client-timeout: 20m0s
    device-uuid: thymos

    from-folder:
        album-path-joiner: '/ '
        concurrent-tasks: 16
        config: ""
        date-from-name: true
        date-range: unset
        exclude-extensions: ""
        folder-as-album: FOLDER
        folder-as-tags: true

    pause-immich-jobs: false
    server: ***
    session-tag: true

    tag: []
    time-zone: ""

immich-go upload from-folder folder_name -k *** --server "https://my-immich.com" --config "/path/to/immich-go.yaml"

Gives me this output:

However, my album only contains 50 images

All images are uploaded but some are not put into the album. There is a hard cut at 50 images. Am I doing something wrong or is this a bug?

Update

Also the session tag feature does not work reliably for me.

This is log output of a simple upload of 48 pictures

But only 26 pictures got the session tag

I have the same issue with custom tags.

[kuzyn]

Do you have the same images in different folders by any chances, or are all your pictures unique?

[Wezea]

Hi @kuzyn those were all unique images.

[Jakeler]

Hmm, can't reproduce it, works in my testing as expected with over 500 files in some albums.
Also does not look like you are using unusual options. Can you post a log and --api-trace log?

[Wezea]

Thanks for reaching out!

I played with some archive folders and uploaded the content like so:

immich-go upload from-folder "2015" "2016/" "2017/" "2018" --server "my-immich.com" --config "/home/user/immich-go.yaml

Some of these buckets have subfolder e.g.

❯ ls -T 2015
drwxrwx---    - user 23 Mai  2024  2015
drwxrwx---    - user 23 Mai  2024 ├──  01-03-2015
.rwxrwx---  85k user 23 Mai  2024 │   ├──  IMG_0068.JPG
.rwxrwx--- 103k user 23 Mai  2024 │   ├──  IMG_0085.JPG
.rwxrwx--- 536k user 23 Mai  2024 │   ├──  IMG_0149.JPEG

@Jakeler

Sorry, regarding the trace log I do have some doubts as it contains a lot of private data.

I just triggered a new upload on a single folder without any sub folders and traced a dry-run.

I see one suspicious request though

https://my-immich.com/api/albums/<id>?withoutAssets=false

Gives me a response with just one existing album on the server with a count of 51 assets in it. It even lists all these assets. I wonder how this is related to my upload. This album is in no way related to the current upload.

[Jakeler]

I totally understand the concerns about personal data, you would have to get random pictures from the internet and try them in your folder structure/server.
Did you get the archive from another immich instance? I have a similar storage template the test import from that data is ok.

https://my-immich.com/api/albums/<id>?withoutAssets=false

The request is normal, it builds an album cache first and reads metadata/asset ids for each album from the server:

immich-go/app/upload/run.go

Lines 179 to 185 in d274f81

	for _, a := range serverAlbums {
	select {
	case <-ctx.Done():
	return ctx.Err()
	default:
	// Get the album info from the server, with assets.
	r, err := uc.client.Immich.GetAlbumInfo(ctx, a.ID, false)

But the cache with max capacity of 50 is likely related:

immich-go/app/upload/run.go

Lines 141 to 146 in d274f81

	uc.albumsCache = cache.NewCollectionCache(50, func(album assets.Album, ids []string) (assets.Album, error) {
	return uc.saveAlbum(ctx, album, ids)
	})
	uc.tagsCache = cache.NewCollectionCache(50, func(tag assets.Tag, ids []string) (assets.Tag, error) {
	return uc.saveTags(ctx, tag, ids)
	})

Normally it calls the save function when it reaches the capacity, but this probably fails in your case.

The log messages to look out for are "updated album" otherwise "failed to add assets to album"
Like this in batches of 50 until it finishes:

2026-01-31 01:37:10 INF updated album album=a assets=50
2026-01-31 01:37:12 INF updated album album=a assets=50
2026-01-31 01:37:13 INF updated album album=a assets=42

Hi @Jakeler , thanks for the detailed explanation.

I setup some test folders and moved a couple of test images in it.

Well, for these folders I see the correct number of images per album now 🤷🏽‍♂️

I'll test this further. Maybe it is related to videos mixed into these folders or RAW files in between (e.g. DNG), which I have not tested yet.

[danielshaman]

I had the same issue. I resolved it by editing the API key and granting the permission albumAsset.create. I then re-ran the import process and I now have all photos uploaded into an album (7000+).

[Wezea]

@danielshaman Thanks for the hint. I might have changed that. Side fact: All images were uploaded all the time, but only 50 were added to the album.
