I got this error while scrolling through a chat, probably at viewing some picture.
I don't know for sure.
I received quite some errors on Fluffychat (Flatpak on Fedora Linux 39) as well, but it was always to long for a bug-report. E. g. it seems to be unable to show code snippets: whenever I open a chat with them a error is shown (unfortunately I cannot copy it), but it displays well as far as I can tell, except very long snippets. They just show like this:

Please add some steps to reproduce this or maybe an example source of an event content. Otherwise I cannot do anything I guess

Whenever I open the chat with this message on Linux (does not have to be on screen, but is one of the last 10 messages and therefore probably loaded), I immediately get an error.
On mobile when opening this chat it does not immediately show the error, only when I scroll up to the message. Note that this is pretty much the same error as on Linux and to long for GitHub.

The error in #828 (comment) I got shortly after opening a different group chat - I have no clue what caused that and could not find a way to reproduce it.

Hm can you try again v1.17.2? I have sent this message as raw json into a room and it worked fine for me:

[XSpielinbox]

I will try it as soon as it is available on F-Droid and via Flathub.

[XSpielinbox]

Yes, at least on Android the rendering bug is fixed in 1.17.1.

[LFd3v]

It looks like that this issue was fixed as of v1.17.3, so it can be closed?

[github-actions]

This issue is stale because it has been open for 120 days with no activity.

[LFd3v]

Another issue that can be closed as of now, it seems.

[XSpielinbox]

I apologize for not answering. It took a while until the new version was available on Flathub and the I completely forgot about it.
Yes, indeed as this seems to be fixed at least in 1.21.2 on Linux Desktop as well, this issue can be closed.
