Today I picked out a second problem case and examined it more deeply with the help of the Joplin debug tool plugin 0.2.0, both on Android and on Windows: The message "Some elements cannot be decrypted" on my Android and the four IDs that are mentioned there.

Using the Android Joplin Debug Tool 0.2.0, I was able to determine the three notes to which these four graphic elements belong. I was unable to find these elements with the Windows Joplin Debug Tool 0.2.0 – I suspect that they no longer exist under Windows and in the Joplin cloud.
I had somehow repaired the three notes recently and was able to remove them from my conflicts at that time. Unfortunately, the same notes have broken again and reappeared in the conflicts.

I will now repair these three notes again or recreate them from the information that can be found:
First, I create a completely new note in the same folder as the defective note and use the same name plus the name extension - new from saved data.

Then I copy the MarkUp content of the defective note manually into this new note in edit mode and replace the MarkUp text of the defective graphic with the MarkUp text of the still functioning note from an earlier version.

I hope that this problem will no longer occur. The reason for my hope is that I followed the advice to disable the OCR function. I even suspect that the current version of the OCR function not only generates a lot of load and thus causes conflicts. I suspect that the current version of the OCR function can also generate errors.

The reason for this suspicion is the strange markup text that I found in the faulty note.

In the good, restored note, this markup text reads


In the damaged note, this markup text reads

This, after removing some invalid/duplicate SVG syntax, renders to:

This makes me suspect a problem with the Rich Text Editor save logic — it converts notes from Markdown to HTML, then back to Markdown when saving.

Things for me (or someone else looking into this) to investigate:

  • How does the Rich Text editor handle the case where attachments are not downloaded? Could this be the cause of the issue?
    • At present, the Rich Text Editor should prevent editing notes where not all note attachments are downloaded. However, it's possible that there is a bug in this logic. Possible fix: Allow editing notes where attachments aren't downloaded; restore the original Markdown for these images when saving.
  • Could the changing resource IDs also be caused by the Rich Text Editor?
    • One possibility is that 1) somewhere, resource IDs are being replaced in notes and 2) when the note is edited in the Rich Text Editor, the "downloading" icon is saved instead of the resource.

ok ...

This hope has already been disappointed today.
Two copies of this newly created note have appeared in the Android conflict folder.
No conflicts can be seen in Windows yet.

OCR was no longer activated – so it can't really be the cause of this problem.

At first glance, I cannot see what the conflict is supposed to be. Both conflicts - notes and their yesterday newly created original - note look the same at first glance - the attached images can be seen correctly in all three

What is totally baffling me right now is that I can watch as 4 more new conflicts are displayed for attachments

My 2024-07-08 - 10:40 pm fork of this is:

Now that I have deleted the elements
from Android using the debug tool,
deleted all notes referring to it from Android and Windows,
deleted all items from both recycle bins,
synchronised multiple times
and selected "Retry all" for the "cannot be decrypted" error message,
all four "cannot be decrypted" error messages disappeared.
The last item
I can still find with the Android Debug Tool, but presumably the "cannot be decrypted" error message only appears if more than one element of this type exists.

Once again, I was mistaken in my assumption.
Another sync later, and the error message for the one element popped up again.

Now I have also manually cleaned up 1f0d03a175134342a61c93e82da9b1fc and all associated conflicts - notes in Android and Windows using the same procedure.

Today I noticed something else while cleaning up the last undecryptable element. This time I documented it in a txt file because the anomaly seems to have arisen in a new Joplin note when I documented it today.

The graphic IDs of the broken graphic elements were not so strangely long in the original note in question. They looked quite normal. Only when I copied the normal-looking non-functioning graphic IDs into a new Joplin note for documentation purposes did they become these strangely long graphic IDs again until a later editing time.

In case it helps you with the analysis, I attach this txt file here.
