Editing notes from Desktop Sync Client creates "File could not be synced" error

[MillironX]

Previously reported as nextcloud/notes-android#1451

Editing notes that have been uploaded from the Nextcloud desktop sync client in either the Server app or the Android app will result in a "File could not be synced due to an error" in the Nextcloud desktop sync client

Steps to reproduce

1. Setup the Desktop sync client on one or more computers

2. Create a new note on the Desktop computer

    echo "# Note From Desktop\n\nThe quick brown fox..." >> ~/Nextcloud/Notes/"Note From Desktop.txt"

3. In the Server Notes app, select "Note From Desktop" in the sidebar, and add the text "Does this work?" to the note body

   

4. Wait for the change to be propagated to the Desktop sync client

Expected behavior

The file ~/Nextcloud/Notes/Note From Desktop.txt on the desktop computer should say

# Note From Desktop

The quick brown fox...

Does this work?

Note that if the edit in step 4 is made from another synced Desktop computer, then the expected behavior is observed.

Actual behavior

The Desktop sync client reports

Note From Desktop.txt could not be synced due to an error

Examining the error report in the settings dialog reveals

Note/Note From Desktop.txt: The downloaded file does not match the checksum, it will be resumed <CHECKSUM> != <CHECKSUM>

The server app reflects the correct state of the files, however.

I can't reproduce this issue. Since the error occurs in the desktop app, I think you should open an issue over there. I'm not very familiar with the desktop app.
