Error in console and blank board

[laurent22]

When opening the board:

VM7048 noteParser.ts:104 Uncaught (in promise) TypeError: Cannot read properties of null (reading 'cards')
    at eval (VM7048 noteParser.ts:104:26)
    at Generator.next (<anonymous>)
    at eval (VM7048 noteParser.ts:8:71)
    at new Promise (<anonymous>)
    at __awaiter (VM7048 noteParser.ts:4:12)
    at parseNote (VM7048 noteParser.ts:49:41)
    at eval (VM7088 useNoteSync.ts:52:67)
    at Generator.next (<anonymous>)
    at eval (VM7088 useNoteSync.ts:8:71)
    at new Promise (<anonymous>)

And then it's empty

I’m seeing the same “blank board after back button” issue on macOS

Environment

• Joplin: 3.5.12 (prod, darwin) on Apple Silicon (M4 Pro)
• YesYouKan: 1.1.3 (current)
• Profile dir: ~/.config/joplin-desktop

What I found
In Joplin’s log / DevTools console, YesYouKan throws a runtime error every time the board view loads:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'split')
    at .../src/utils/processRenderedCards.ts?:92:41

I also see:

• PostMessageService: Cannot receive message because no viewMessageHandler was found
• then the board view keeps reloading and stays blank.

So it looks like the board rendering / card processing path is crashing (likely on some card content the plugin doesn’t expect).

What I’m trying next

• Downgrading YesYouKan to 1.1.2 to confirm if this is a regression between 1.1.2 and 1.1.3.
• If needed, I’ll share the note content pattern that triggers it (once I isolate which card causes the split() on undefined).

If there’s a specific debug build or a logging flag you want me to enable inside the plugin, tell me and I’ll run it.

One of my "card" markdown "broke" the rendering. I fixed by going column by column, card by card and by cutting & paste until I found which one.

It was a card containing some mardown with tiple backquote ``` ...

Reverting to previous versions was challeging, I used my local Backups as I could not org.joplinapp.plugins.YesYouKan.jpl for previous versions in github. But it did not work

[laurent22]

Thank you for looking into this and providing the technical info. Maybe we need to escape triple backtick in the card content to prevent any issue. It's because the board settings are also within a triple backtick block. That may mean it's not possible to render code within cards, but that's better than breaking the board
