This happens on half the tries. It does not generate errors in the console.
Maybe it could be a concurrency issue. I've looked at the snapshot data and it's correct.
My Workaround is force sync again (works with it) ๐ค
const ydoc = new Y.Doc()
this.provider = new HocuspocusProvider({
url: `ws://localhost:8000/workspace/v1/documents/${this.document.id}`,
name: String(this.document.id),
document: ydoc,
onSynced(data) {
console.log(data)
},
})
this.provider.on('connect', () => {
this.provider?.forceSync()
})
this.editor = new Editor({
extensions: [
StarterKit.configure({
history: false,
}),
Collaboration.configure({
document: ydoc,
field: 'content',
}),
CollaborationCursor.configure({
provider: this.provider,
user: { name: this.getRandomName(), color: this.getRandomColor() },
}),
],
}
Thanks in advance for your attention, Stefan!
Your project is amazing!
Currently, YDocs are in-memory and persisted only when the room is empty or the worker shuts down.
Here are some other Yjs persistence implementations:
A common theme is writing incremental updates and consolidating later.
Maybe creating an implementation for yrs-persistence
in yroom
might be the way to go.
Seems like a pretty simple setup to me. ๐
This error appears in the new version, and I confirmed it with commits and debbug

Debug:
OBS:
I tried to use the command with the --channel configuration but it gave parsing error
For some reason, after a while the worker crashes and/or it crashes after some error.
I noticed that sometimes this happens, because there was an error, and the worker stopped responding after this error.
For example:
class YDocUpdateManager(models.Manager):
def get_snapshot(self, name):
try:
data = self.get(name=name).data
return bytes(None) # <<<<<<<
except YDocUpdate.DoesNotExist:
return None
def save_snapshot(self, name, data):
return self.update_or_create(name=name, defaults={"data": data})
This also happens when the active worker spends some time, I imagine that it is an error that happened and it is holding the response due to asyncronism.
Note: I already adjusted for the new update
I've been following each Update and I'm finding your project amazing. Thank you for your attention and initiative!
Hello Stefan, how are you?
Is there any way to edit YDocs directly instead of using YRoomDocument export?
The purpose of this is to be able to handle YDocs directly the way they are on the server side.
Thank you for this package, definitely helped me get TipTap/YJS working with my Django app.
I seemed to have come across an error where it seems as though a corrupted document state is being persisted causing both the loading of the document to not work as well as the yroom worker to crash.
Below is the relevant stacktrace:
app[rtc.1]: [INFO] yroom.roomsync: Creating new YRoom 'sequence.2868' with data and settings YRoomSettings { protocol_version: V1, name_prefix: true, server_start_sync: false, disable_pipelining: true }

I don't believe there is a way to recover corrupted documents from the saved bytes data?
The only relevant link I found was: y-crdt/ypy#101
Which seems to be referencing a much older version of packages and was from a few years back?
Any ideas that you may have would be appreciated!
Thank you
