Create post with markdown date returns error 500

Product Support

AI-generated summary

User nobodyfrm reports a 500 error when creating a post with a markdown date via API or frontend, traced to a moment.tz is not a function error in pretty_text.rb. pfaffman asks if it works in the UI and whether third-party plugins are involved. nobodyfrm confirms it fails in the frontend too and lists installed plugins and themes. nat asks for the Discourse version and notes the raw post formatting looks malformed, requesting a screenshot or video. nobodyfrm shares screenshots showing the date renders as quoted text, not a proper date widget. Later, nobodyfrm resolves the issue: some plugins were outdated because they’re now included in Discourse core; updating them fixed the problem. jdc20181 notes this may not apply to their case, as they updated Discourse recently and still face the error, referencing a similar issue on Discourse Meta.

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: <myKey>” -H “Api-Username: nobodyfrm” -H “Content-Type: application/json” -d ‘{“topic_id”: 553,“raw”: “CSD Limburg 2025-05-10T00:00:00Z”}’

Does it work if you do it from the UX? Do you have any third post party plugins?

no, it dont work from the normal user ux/frontend.

What Discourse version are you on?

Your post raw looks funky here. Can you confirm you wrote this

curl -X POST `https://forum.example.com/posts.json` \
-H “Api-Key: <myKey>” \
-H “Api-Username: nobodyfrm” \
-H “Content-Type: application/json” \
-d ‘{“topic_id”: 553,“raw”: “CSD Limburg  `` [date=2025-05-10]`”}’

Or share a video/screenshot of what you are typing in the composer.

5

your curl creates a post but the date is quoted text - not a date.

i found my mistake: Some plugins are now included in discourse core so the plugins was outdated.

After I fixed this it works as expected.

8

I am not sure if this is the solution for me since I have had it happen after updating Discourse thus, any core plugins should have updated with discourse in my case.

Reference my Post:

Internal Server Error - Time/Date Insert - Support - Discourse Meta

Someone referenced this one, but while I think its related, I don’t know if its 100% the same.
