So:
All i did was hit update all then i went to check the logs then went to admin on a user then hit back to forum and got this message.
What happened?
**Edit**
Just opened it in a new tab and it worked what’s happening?

Check your /logs page?

There seem to be two different things in those logs.
The `ActionView::Template::Error` / `Propshaft` lines about a missing `chunk...js` asset may explain why this happened immediately after “update all” and then worked in a new tab. That looks like an old tab trying to load an asset filename that no longer exists after the update/rebuild.
The separate line:
```plaintext
NameError (uninitialized constant ReactionsSerializerHelpers) app/serializers/post_stream_serializer_mixin.rb:31:in 'PostStreamSerializerMixin#post_stream'
```
looks like the bundled discourse-reactions issue I reported here:
> [@NameError: uninitialized constant ReactionsSerializerHelpers when loading topic posts](https://meta.discourse.org/t/nameerror-uninitialized-constant-reactionsserializerhelpers-when-loading-topic-posts/403692/1):

The error appears to come from the bundled discourse-reactions plugin while serializing the post stream. The site reports the message as 8 copies reported. I checked the compare range below, but it does not look like it touches the failing backend code path, so I am reporting this separately: play_button Error message from /logsplay_button Backtrace from /logs What appears to be happening The er…
I also opened a PR here:
[https://github.com/discourse/discourse/pull/40255](https://github.com/discourse/discourse/pull/40255)
So I would treat the Propshaft asset error as likely stale-tab/update fallout, and the `ReactionsSerializerHelpers` error as a separate backend reactions-plugin issue.

You’ll need to rebuild from the command line.

Explain what you mean by that?

It’s easier for me to type than to do a search and find a topic explaining it. 😿
