Markdown Parsing Problem with Netlify CMS

ozgurozan · September 21, 2021, 4:55pm

Hi there!

I’m having parsing problems with copy/pasted rich text content on Netlify CMS. It’s an issue happens in every few months that I have to fix the it manually because Netlify doesn’t build the app after the client create new content.

I share below the latest .yaml data preventing the app from building. I checked it with both a YAML and a Markdown validator, and it seems it’s valid. From the error message guessed it’s something to do with kramdown. Can someone enlighten me about the issue, because I couldn’t figure it out.

Here is the error I got from build --verbose.

I found the answer on the thread below, you need to pass a context to the helper method:

def markdown(text)
  Tilt['markdown'].new(context: @app) { text }.render
end

In case you’re looking for such a thing: I’ve got a couple of starter templates with examples on my github (featuring that exact bit of code, actually)

Thank you @tomrutgers,

I checked your Github and realized that already using your template. But your code doesn’t pass this (context, @app) to the Tilt.new function. Therefore I had to add it.

Thanks a lot.

Ah, I thought I did, but it seems I forgot to update one of my templates. The webpack one (which kinda became my standard) does pass context:

github.com

tomrutgers/middleman-webpack-netlify-cms/blob/master/config.rb

# Import custom libraries and helpers
Dir['./*/*.rb'].each { |file| load file }

# Load Sass from node_modules
config[:sass_assets_paths] << File.join(root, 'node_modules')

set :css_dir,    'assets/stylesheets'
set :fonts_dir,  'assets/fonts'
set :images_dir, 'assets/images'
set :js_dir,     'assets/javascripts'

# Activate and configure extensions
# https://middlemanapp.com/advanced/configuration/#configuring-extensions

activate :external_pipeline,
         name: :webpack,
         command: build? ? 'yarn run build' : 'yarn run start',
         source: 'dist',
         latency: 1

I see, I guess this one is more contemporary because of webpack, isn’t it? Maybe I’ll switch to it completely.

Thanks a lot.
