What issue do you have?
Hello,
I am having a synchronization problem with Joplin Desktop 3.7.18 on Windows, using Infomaniak kDrive via WebDAV.
The problem affects two Windows computers (my desktop PC and my laptop).
However, Joplin on my Android phone and tablet works correctly, including the images and other attachments.
I would like to understand whether this is a Joplin Desktop issue, a WebDAV issue, or an interaction between Joplin and the WebDAV server.
What happens
The notes themselves synchronize correctly.
The problem is specifically with resources / attachments such as PNG, JPG, MP4 and other files.
On the Windows computers, Joplin creates the local resource files in:
.config\joplin-desktop\resources
but many of these files have a size of:
0 bytes
So the file exists locally, but the actual binary content has not been downloaded. As a result, the images cannot be displayed correctly in Joplin or in Windows Explorer.
Error shown by Joplin
In Joplin DevTools / Console, I repeatedly get errors such as:
ResourceFetcher: Could not download resource
TypeError: Request path contains unescaped characters
I also previously received:
Trying to upload resource, but only metadata is present
Several resources are affected. For example:
8a8421004e2e476f92a81d1bad27fedd
0049e8eeb82045319ab62e13cb3e1162

I checked the WebDAV target directly
I did not modify anything on kDrive. I only inspected the synchronization folder.
The Joplin synchronization target on kDrive contains the hidden folder:
.resource
This is different from the local Joplin folder:
resources
I initially wondered whether the different names were a problem, but I understand that these are different locations used for synchronization and local storage.
More importantly, I checked the actual resources on kDrive.
For example:
Resource ID:
8a8421004e2e476f92a81d1bad27fedd
The corresponding metadata on kDrive reports:
mime: image/png
size: 2901044
type: 4
So this resource exists on kDrive and has a real size of approximately 2.9 MB.
I also checked several other problematic resources in the .resource folder on kDrive. They have real, non-zero sizes, for example several megabytes.
However, the corresponding files in the local Joplin resources folder on Windows are sometimes 0 bytes.
This is what seems to happen
My current understanding is:
Joplin metadata is synchronized
↓
Joplin knows that the resource exists
↓
Joplin creates the local resource file
↓
Joplin tries to download the actual resource data
↓
the download fails
↓
the local file remains at 0 bytes
↓
the image/file cannot be displayed
The error:
Request path contains unescaped characters
makes me wonder whether the problem occurs when Joplin Desktop constructs or sends the WebDAV request for some resources.
Important observation
The same general data works on my Android phone and tablet.
The problem happens on both Windows computers.
So this does not look like a simple case of the files being deleted from kDrive.
I have also checked Joplin's synchronization reports and found that some resources remain unsynchronized while the notes themselves continue to synchronize.
Version
Current version:
Joplin Desktop 3.7.18
Windows
Infomaniak kDrive via WebDAV
I also tried an older Joplin version (3.6.15), which had worked correctly for me in the past, but it no longer restores the images correctly in my current synchronization environment. I therefore returned to the current version.
What I would like to know
Could this be a known Joplin Desktop/WebDAV issue where the resource metadata is downloaded correctly but the actual resource content fails to download?
In particular, could the error:
Request path contains unescaped characters
cause Joplin to create the local resource file while leaving it at 0 bytes?
I would also like to know whether there is a safe way to diagnose this without deleting or modifying the resources or the Joplin database.
I have backups of my Joplin data and I am not modifying or deleting the problematic resources while investigating this.
I can provide:
- sync reports,
- DevTools error logs,
- resource IDs,
- screenshots of the local
resourcesfolder, - screenshots of the kDrive
.resourcefolder.
Thank you very much for any help or suggestions. I am mainly trying to determine where the failure occurs: Joplin Desktop, WebDAV, kDrive, or the interaction between them.
