Spreed: Group chat "Cannot read property 'label' of undefined" (Chromium only)

[tristanlins]

Steps to reproduce

1. Open Nextcloud in Chromium
2. Open a group chat

Expected behaviour

The chat history should be displayed.

Actual behaviour

Only the list of participants can be seen.
The chat history is empty or the chat history from the previous chat is still visible.
=> Chat history is not updated to the group chat.
Instead, a JS error occurs. (see Browser log)

The error also occurs in Incognito mode. (browser apps disabled)

Works fine in Firefox.

Looks like it's an error from the change name field

[tristanlins]

Here are two screenshots of the current state:

Let me know if you need more feedback 😀

[danxuliu]

@tristanlins Are you using by any chance the experimental web platform features of Chromium? Either by running it with chrome --enable-experimental-web-platform-features or by enabling them by visiting chrome://flags/#enable-experimental-web-platform-features.

[tristanlins]

Looks like 🙈
Sometime in the past I have to activate and forget this. 😬

[tristanlins]

I disabled the experimental features and now it works again.
Should the issue remain open to correct this for future versions?

[danxuliu]

Sometime in the past I have to activate and forget this. :grimacing:

Great that you forgot it as it allowed us to find the bug before it was widespread :-P

Should the issue remain open to correct this for future versions?

It will be automatically closed once #2063 is merged ;-) Thanks!
