This issue has happened right after the latest upgrade to v3.3.0.beta1-dev — ac53e5a962 — Ember v5.5.0. Link to my custom plugin’s markdown extension rule: Files · master · Text Blaze / Discourse Snippets · GitLab (unchanged since almost an year) Older posts with this extension are still rendered correctly. But, doing “Rebuild HTML” on any old post will break it. Link to example post with the issue: link I believe the issue is not related to the plugin, as the plugin is unchanged, and the extension works fine when drafting the post. Is there anything specific in this latest Discourse upgrade that can cause this issue? Description: I have a custom plugin that uses markdown extensions (as described here). The plugin works when drafting a post/topic - showing the HTML preview. But, when the post/topic is posted, the plugin simply has no effect. The raw post contents are preserved as it is. Screenshot: works while drafting [image] Screenshot: raw code after posting [image] There are no (relevant) errors in the DevTools or in the forum /logs endpoint.

Thanks for the report @GaurangBlaze. Looks like a recent refactoring broke support for .js.es6 files in the server-side markdown cooking. We’ll get it fixed up in the next few days. In the meantime, removing the .es6 extension from your JS files should resolve the problem. That’s a good thing to do anyway - there is no longer any need for it, and using the standard .js makes for much better IDE/editor support.

Hi @merefield , thanks for your response. Sorry about the confusing wording of my original topic. The issue is with my custom plugin that uses Discourse’s Markdown extensions. I have now edited my original post to reflect that.

Ah! Probably I misread too, thanks for clarifying!

This plugin may have several issues. These are the ones that pop up on the console: [image] One of them refers to a removal in 2.7.0!! Are you the maintainer of this plugin? If so I think you have some work to do :slight_smile:

Yup, I am the maintainer :slightly_smiling_face: Though, I don’t feel these two warnings are related to the current issue. The whiteList method is still available in the latest discourse. And the other deprecation is related to a toolbar entry in the GUI, not the actual markdown extension. At least, that’s my thought. I will still push an update to handle the deprecations. I will also mention that the plugin was working fine until the previous release.

It’s still working though? What appears to be missing is any CSS to style it? [image]

Oh yes … this must have happened very recently (last 4 days!) Just updated my dev instance and can finally repro … apologies!

Yup I think it was probably DEV: Remove sprockets from plugin 'extra js' pipeline (#25502) · discourse/discourse@1757a68 · GitHub (4 days ago)

Core behaviour has been fixed in FIX: Restore support for `.js.es6` files in PrettyText (#25588) · discourse/discourse@dea753a · GitHub (but still, I recommend keeping the .js extension. We will eventually deprecate the use of .es6)

Thanks. I didn’t find the .es6 deprecation in the /logs page of our community. Do you plan to put this deprecation there (and other similar deprecations also)?
