I just performed a update to the latest version of discourse (test-passed). After that update, I get an error message when accessing any topic in the forum. Something that translates to: Sorry, we couldn’t load the topic – probably due to a connection error. Please try again.
The production logs keeps showing
```plaintext
Completed 500 Internal Server Error in 439ms (ActiveRecord: 425.3ms)
LocalJumpError (unexpected return)
/var/www/discourse/lib/plugin/instance.rb:188:in `block (2 levels) in topic_view_post_custom_fields_whitelister'
```
for almost all requests.
Any help would be appreciated.
Rebuilding the app did not help.

What plugins do you have installed?

Do you have any other plugins installed, but disabled?

That was the list from app.yml. I don’t know any other place where plugins could be specified.

I have just created a fix, it will take a few minutes to reach `tests-passed`
[https://github.com/discourse/discourse/commit/467c5299207636b2d9f966885c81d8b167283103](https://github.com/discourse/discourse/commit/467c5299207636b2d9f966885c81d8b167283103)
However, none of those three plugins make use of this particular part of the code, so I am unsure why the error is occurring for you.
@some-user it’s now in tests-passed, so please try updating again and see if that fixes the issue.

If you want to look into that and I can do anything to support, let me know. But as the patient is alive again…

Good to hear 🙂

I have one idea - do you have the built-in “polls” plugin disabled? (check the `poll enabled` site setting). That would explain it.

Mystery solved! 🕵️♂️
(now that the bug is fixed, it is perfectly safe to leave it disabled if you want)
