Upon adding a folder to sync in Windows 11 to my Nextcloud 22.2.5 a few files gave this error also:

can’t update non existing placeholder info

The files were uploaded, so in effect nothing seems wrong, only the error itself!?

I could resolve the error in a crummy way:

  1. delete the files locally
  2. force a sync => all is well
  3. restore the files from windows trash
  4. force a sync => all is well, including the loss of the faulty(?) error

I also tried "occ files:scan --all" This did not fix the error. I think there was something going wrong in the desktop application?

AD: what I noticed was that most of the dozen errors were images where windows did not show a preview of. Opening the file did work however and showed an image (one was a wmv file). Might it be something with content type (detection) preview?

I have the same issue on a fresh install of 23.0.3 and Windows 10 client 3.4.4 but it's only failing on one file, a 4GB .iso file. I thought maybe it was something to do with the default limits on file sizes so I increased the max memory to 2GB, and max filesize and max POST size to 10GB in php.ini (system resources aren't an issue), but it's still failing on that one file with the "Can't update non existing placeholder info" error.

I replicated the problem on Windows 11 NC client 3.5.1 connected to NC 24.0.0 running on TrueNAS Scale (official repo).
When I copy a 4,2 GB file to the local NC folder, it syncs correctly to the server folder, which is a local external storage (the file is visible on the web interface).
But since then, the Windows client continues to prompt "Can't update non existing placeholder info".

I also have this issue on Windows. The file should be synced to external storage. It is not a large file (<10MB).

Same issue here. Running Win 10 21H2 with Nextcloud Client 3.5.1.
The nextcloud instance is hosted externally with version 24.0.1.1 .

Get this for thousands of files (and various file-types).
Moved folders into the synced folder and these messages appeared after a while.
The client then goes through these files and at the end it seems to freeze for some time until it starts again.

Does this error-message has something to do with the virtual files?
I think the folder had been marked to free up local space before and I then put new files in there.
Nextcloud actually has two options to handle that:

  1. Upload the files and immediately replace them by virtual files
  2. Upload the files and keep them locally, since the have not been flagged for being deleted explicitely

Not sure which way was chosen here, but the error message sounds more like 1.).
Maybe there is an error in this such that the client "thinks" that there should already be a virtual file and that it just has to update something compared to creating a new one.

Please let me know if I could help by testing something.

it is annoying as it just stops the sync...

I have the same issue, usually it's a single, rather random file (e.g. some file last modified 2 months ago)...

I have had same or similar errors. I suspect that in my case, the problem could be related to editing metadata of selected photos. Reconstruction of what I did, if anyone is interested on:

  1. Photos are uploaded from mobile to a specific directory on my Nextcloud server.
  2. This directory is replicated to my Windows notebook as a Virtual File System (VFS) directory.
  3. During a periodic cleanup action, I noticed that some photos did not have GPS coordinates due to having the corresponding setting inactivated on the phone.
  4. I immediately COPIED the affected photos with original timestamps to a temp directory outside the VFS structure.
  5. There I assigned the correct GPS coordinates and saved the files with their ORIGINAL FILE TIMESTAMP.
  6. Then I MOVED these photos back to the VFS directory, thus overwriting the original files there.

From this point on the issues with the synchronization started, first with the error message "Can't update non-existing placeholder info" for mentioned photos, but also with never closing file download process messages or also with remaining status bars on the Windows Explorer for long since completely downloaded files - the whole synchronization mechanism apparently didn't quite cope with the situation anymore.

I solved the problems by moving away the mentioned modified files, which, by the way, were easy to recognize by their status with the two blue arrows pointing in opposite directions (sync pending?), in order to move them back after a short waiting period to assure that the synchronization of the moving outside step had been completed.

My environment: Debian Sid (Testing V12, Bookworm); Redis Server 7.0.5; MariaDB 10.5.12; STUN/TURN Server (coTURN) 4.5.2 'dan Eider'; PHP 8.0.24; NGINX 1.23.1; Nextcloud Server 25.0.0.18; Nextcloud Desktop Client V3.6.1 on Windows 10.0.19045

There is also the following open issue, which has similarities with the case described here: [Bug]: Couldn't convert to placeholder #4401.

It may well be that this error is a rare corner case, but I think it would be good if someone from the development team (@mgallien, @allexzander, @claucambra) would briefly look into this.

Best regards.

I got this error for hundreds of files when I replaced them with identical files containing older timestamps than the previously synced files.

Seems this and the related Bug are automatically closed because no one cared to solve it.
Is there a way to reopen them?

I have seen some pattern in this. When dragging a folder to nextcloud folder, and a windows want's an "folder exists, do you want to merge" to happen ... if you choose yes and replace existing files - sync is OK, if you choose to skip existing files, the error Can't update non existing placeholder info results.

Experiencing the same with:
client 3.8 on Win 10 Enterprise 22H2
server 26 with external storage CIFS on Windows Server 2022

the error logs on the server are not realy conclusive

Experiencing the same with:

clientVersion=3.8.1stable-Win64 (build 20230419)
serverVersion=25.0.5.1

uninstallation, installation of the client doesnt fix the issue

Any update, workaround ?

We have the same issues with some windows clients.

client= 3.9.0
Server = 26.0.2

@CKaschig

Same here with Server = 26.0.3 / Client 3.9.0.20230613

Real nasty - houndreds of lines with

  • Can't update non existing placeholder info
  • Couldn't convert to placeholder
    below header line 'Synchronising VirtualFiles with local folder'

In our case, the NC client has errors, but the data was synced to the NC Server successfully

We found a workaround

In the Nextcloud client :

1 Re-add the same account that encountered the issue
2 Select a new folder to sync the data from the NC server
3 Let it sync to the new folder

At this point, the "new" account in the new folder will have the new data synced without the error
Make sure of this, once you are sure, you can delete the old account

Latest Release, still this error occurs.
Move files, sync and move back just makes the error return.
This bug seems to be presebt since years and should have priority

@alexx-ftw This was releaed in v3.10.0 (#5890) and v3.9.1 (via a backport: #5906). If you're still experiencing this it's a different or additional issue. Please open a dedicated issue.

fresh installation, win11 and not VFS folder with all the files from previous cloud solution.
synchronization took 21h
finished without problem
suddenly 2 small .doc files start throw this error - but they were synched with (next)cloud but no matter what every sync action results in cfapiwrapper.cpp:868 ]: "Couldn't convert to placeholder"
Solution:

  • I moved those files one-by-one outside sync folder
  • as Im the "owner" those files were deleted from (next)cloud
  • I manually sync folder - with success
  • I moved those files back to original folder structure
  • I manually sync folder again and again with success
  • No issue for me for now
