Bug? forum issues

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:

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

my Discourse version is 2026.5.0-latest.1 (fbcbdc46d8) I am seeing repeated /logs errors when loading topic posts. 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: Error message from /logs Backtrace from /logs What appears to be happening The er…

I also opened a PR here:

Fix reactions serializer helper loading (#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.
