We experienced this issue on a discourse site that was not updated. An update seems to have mitigated the issue for now but we’ll be keeping an eye in case it shows up again.

Yes this error is surprising, can you confirm me which version of Discourse you are using please?

We are using `version: latest-release`
When we encountered this issue was discourse version `https://github.com/discourse/discourse/commits/v3.3.0.beta2`
and we didn’t experience this after updating to version `https://github.com/discourse/discourse/commits/v3.3.0.beta3`

It appears my site is on version `3.3.0.beta4-dev`. I assume this isn’t supposed to be for production? I see the dev suffix.

It is supposed to be used in production. Communities hosted by Discourse also get those “dev” versions.
The dev suffix only indicates that this is not the final version of 3.3.0-beta4

> On tests-passed, starting with 3.2.0.beta1-dev, Discourse core version numbers will include a `-dev` suffix to indicate that they’re not the final ‘release’ versions of a beta.

Once the final version of `3.3.0-beta4` comes I’ll be sure to update and try again. This appears to only happen on specific posts using a special template, although we didn’t encounter any issues with it before. It’s just comprised of `` buttons, `[details="Summary"][/details]`
`, and images. Nothing experimental, just core Discourse functions.

I have an update, I managed to find the cause. If I insert a date and time such as `[date=2024-07-23 timezone="America/New_York"]`/2024-07-23T04:00:00Z it will return the 500 error.
Does anybody know a fix? Thanks.

Which version of discourse are you using? Do you know the commit? You can find it in the source page of your forum:
Also does it happen in [/safe-mode](https://meta.discourse.org/t/use-safe-mode-to-troubleshoot-issues-with-themes-and-plugins/53504) ?

Hello, for your question on which version it is `3.3.0.beta5-dev`. For your question on the **[safe mode](https://meta.discourse.org/t/53504?silent=true)** aspect, when I enter [safe mode](https://meta.discourse.org/t/53504?silent=true) the button to insert the date/time disappears. I think this is related to the [Discourse Calendar (and Event)](https://meta.discourse.org/t/discourse-calendar-and-event/97376) plugin.

Fun fact :discourse: - The insert date feature is part of the Local Dates plugin, which comes bundled with Discourse (along with some others like Discobot, Hide Details, Chat, and so on). Unfortunately, with it being a plugin, [safe mode](https://meta.discourse.org/t/53504?silent=true) no\_plugins would disable it just like other optionally installed plugins. ☹
There is an option to enter [safe mode](https://meta.discourse.org/t/53504?silent=true) with only non-official plugins disabled, along with disabling themes and theme components, which might be worth a shot?

Unfortunately even with those settings applied, same message still pops up.

I’m pretty sure this is something in your env. Do you know if other people on this forum can do this or if you are the only one with this error?
Also try to look at the network tab of your browser console, and also the console directly to look for any error.

I’ve asked another person on the forum and they also said they received an `Internal Server Error`.
I also receive this in the console when I try to post.

Perhaps related?
You can trigger a runtime error in `discourse-local-dates` if you enter a wrong timezone in a `date-range`:
`date` works with wrong timezone:
`[date=2024-07-25 time=14:05:00 timezone="Europe/Berlinx"]`
2024-07-25T14:05:00Z
`date-range` does not:
`[date-range from=2024-07-25T15:00:00 to=2024-07-25T17:00:00 timezone="Europe/Berlinx"]`
2024-07-25T15:00:00Z→2024-07-25T17:00:00Z
From here on, other dates will not be parsed:
`[date=2024-07-25 time=14:05:00 timezone="Europe/Berlin"]`
2024-07-25T12:05:00Z
