Markdown JS with two protocols

Version: 2.7.0.beta1
Install: discourse-docker

Hi everybody,

dont know how to better describe this but the markdown-it js bundle in our discourse installation is not correctly working. Somhow we get an additional protocol “https” added to the URL of the javascript (served via CDN and saved in our S3 bucket)

I added a screenshot.

Alll the other ressources are working fine

Its just this and due to this, we dont get a preview function :frowning:

Thanks for your time and looking forward :slight_smile:

Are you running behind a reverse proxy? Have you set force_https on the settings?

yes, force_https is set. And no, no reverse proxy apart from the inbaked nginx.

What is weird is the fact, that the other JS are working fine, with the CDN url. Its just the markdown-it…

I dont know where to look in the code, not that i know ruby. :slight_smile: :grinning:

Something weird about your setup.

You have a S3 CDN setup, but it is on the same URL as the bucket?

data-s3-cdn="https://discourse-dev.assets.schwarz" 
data-s3-base-url="//discourse-dev.assets.schwarz"

Comparing with Meta:

data-s3-cdn="https://d11a6trkgmumsb.cloudfront.net" 
data-s3-base-url="//assets-meta-cdck-prod-meta.s3.dualstack.us-west-1.amazonaws.com"

The code that load dynamic scripts will try to replace the S3_BASE_URL for S3_CDN:

ja both URLS are the same, as we use Minio for an s3-compatible object storage.

@Falco, you where right. Seperating both urls helped to fix the issue :slight_smile:

Thanks for the help :slight_smile:
