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.

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?

[image] tobiaseigen: [date=2025-08-15 timezone="America/Los_Angeles"] Edit: I will post the markdown soon. I didn’t have the button pressed. :sweat_smile:

Quelqu'un sait-il ce qu'est cette erreur MiniRacer::RuntimeError (TypeError : moment.tz n'est pas une fonction) ?
