I’ve been getting this error frequently now and it’s beginning to become a large annoyance. Running ./launcher restart app temporarily resolves the issue, but after a bit it will return. [This image depicts a screenshot of a coding environment displaying a list of code snippets in white text on a black background. (Captioned by AI)] I get this error when I edit posts especially, I’ve had a history in the past where if a Date/Time stamp is inserted such as this → 2024-11-11T05:00:00Z (UTC), then it would result in the error. Can someone please examine this error and figure out where the source is, or if anyone has encountered this before know a better workaround? Thanks.

I am getting an Internal Server Error for the Time/Date Insert. This has happened before, I am not sure what I did to fix, probably just a server restart - but I thought maybe its a good idea to make a topic about it since my last issue was resolved by speaking up about it.

HTTP HOSTS: EDIT: Manually rebuilding resolved this, but since its happened before I am still curious on preventing again in the future.

The issue has also been encountered here [imagen] Create post with markdown date returns error 500 Support Hi, when I try to create a post with markdown date i’ll get an error 500. This error trigger via normal frontend post also! What i’m doing wrong? curl -X POST `https://forum.example.com/posts.json` -H “Api-Key: ” -H “Api-Username: nobodyfrm” -H “Content-Type: application/json” -d ‘{“topic_id”: 553,“raw”: “CSD Limburg 2025-05-10T00:00:00Z (UTC)”}’ Logs: Message (11 copies reported) MiniRacer::RuntimeError (TypeError: moment.tz is not a function) lib/pretty_text.rb:238:in `eval' lib/…

While that is the same error (500), I do not think it’s the same situation(even though similar), since my issue happened after I updated Discourse, which should have updated core plugins as well. The OP of that topic - said they updated a core plugin to fix - while I updated the entire platform - and it happened after an update.

Issue happened again today this time without any update being done prior to the error occurring. Still hoping for someone to respond with a solution.

can’t believe this is being ignored. I am still getting the ERROR - Chat GPT says its something to do with a missing Import :upside_down_face:

Can you provide step by step replication steps? How are you arriving at this error message? Is your site self-hosted? If so, can you confirm you’ve recently done a rebuild from the command line and your site is up to date, and you are still able to replicate?

The issue happens when users are creating topics and inserting a timestamp. They insert the timestamp, and the error occurs when they press “Post” or “Edit” a post I believe. I personally cannot reproduce it. The information I provide is from the Error logging information, and what my moderators are reporting to me. Yes, it is self-hosted and resolves on its own when I rebuild but the issue seems to always return. For the last week it’s been a daily return. For context - I use Discourse for my small moderation team to log actions performed within our community - so we use the date/time insert every time we log something. I have more of the details from the error log if you need them. [image]

can you share the markdown here for a post that generates the internal server error message?

We use the button within the composer and not insert through a markdown format, so I am unsure what you are looking for. For context, its hard to reproduce, but happens frequently. I have to update Discourse or rebuild to stop the error. I have narrowed it down to the Date/Time plugin as you can still post without it - which brought me to here. Thanks!

I am trying to get replication steps. If you have a post with just the below markdown, what happens? [date=2025-08-15 timezone="America/Los_Angeles"] I will post that below and see if I can replicate your problem here. It appears I cannot. What does the markdown for your inserted time/date look like?

¿Alguien sabe qué es este error MiniRacer::RuntimeError (TypeError: moment.tz no es una función)?
