The server is running the 2.8.0.beta6. All other features are working. Groups listing also works, but when clicking on any specific group gives the following error.
Server Error
while trying to load [/groups/.json](https://example.com/groups/%3Cgroupname%3E.json)
Error code: 500 Internal Server Error
The log tells that it is report\_js\_error
It is critical since group functionality is down. Any clue on how to fix the problem will help. Thanks in advance.

The problem became more critical. Cannot read any topics now. The following error message appears:
Sorry, we couldn’t load that topic, possibly due to a connection problem. Please try again. If the problem persists, let us know.

Have you tried [safe mode](https://meta.discourse.org/t/how-to-use-discourse-safe-mode/53504)? You’ll also want to check your [logs](https://meta.discourse.org/t/where-does-discourse-store-and-show-logs/58022) and probably provide those.
Even with those I personally can’t help you, but without trying those two things there isn’t much for anyone who can to help you with.
My personal self-hosted instance and a CDCK hosted instance I manage both load groups JSON files fine ( I just checked) when on latest.

Thanks. Exploring through safe-mode also gave the same error. Should I rebuild the container after commenting the plugins?

I don’t think you need to comment out the Plugins if you disabled them in safe-mode and the problem persisted. An upgrade and a rebuild might do the trick though. :+1:

Thanks.
Before posting the topic, I did `launcher rebuild image-name`. The errors persist after that.

Does that do the same job as `./launcher rebuild app`?

I think so. It should create a container called ‘app’.

Ah, I see. I’m afraid I only know the basic ‘turn it off, and turn it back on again’ run-through -
- Check it in safe-mode
- Upgrade to latest
- Rebuild app
Is there anything special about your install that may give someone else a clue as to your issue?

You saved it. This is it. Upgraded to the latest (aba08d1929) and the problem is solved. But the latest release (2.8.0.beta6) didn’t fix the issue.
Wondering why this issue did not crop up on other discourse instances that we are running which are all at 2.8.0.beta6.
