Searched a bit but I didn鈥檛 find any open issue for that.
In any thread, write:
- Foo
- Bar
It will get formatted properly in the chat bar, as shown here:

But once you send it, it gets deleted (potentially losing a long message) and this error shows up:

I don鈥檛 really have the time to look into it but:
1) It鈥檚 a pretty cryptic error message IMO
2) Losing what you just wrote is really annoying (I think you should clear the chatbar only if sending a message succeeds?)
Thank you for reporting this! @mxstbr can we hot fix this?
Oh yeah we should remove lists from the block configuration of the markdown plugin of the chatInput! I put them in, didn't like them but apparently forgot to take them out.
@mxstbr i removed ordered-list-item, unordered-list-item from markdown plugin configuration object. but still i am able to see formatted list in chat input.
i think there is a bug in draft-js-markdown-plugin
That's fine, submit a PR! I can fix that if it really is
@mxstbr after merge, i pulled latest alpha and installed dependencies, it worked. but i don't know why it was not working before.
