I'm try to intergrate into our product, but I found a problem:

I'm going to need a minimal reproduction to debug this. Can you set up a CodeSandbox or repo that reproduces this error? Or at least the full JSON of your data snapshot instead of a screencap?

[Alex Kreidler]

I've got the same error. I made a CodeSandbox example.

Reproduction steps:

1. Open devtools
2. Click on test
3. Click on test2. You should see the error in the console
   (You may have to open a second tab with the same page before step 2/3)
4. If you repeat clicking on any of the text items you should see the error repeat

I initially thought it might be an issue with the immer Zustand extension. But I removed it from the code and still got the error.

Thanks Alex!

From debugging your example, the bug is obvious: I forgot to convert strings to YText objects before shoving them in Yjs...

I'll get that fixed as soon as I have the time!

Release 1.3.1 fixes this issue, so going to close for now. If something else is broken, don't hesitate to reopen it!
