Error: The language "markdown" has no grammar

[YassinEldeeb]

After installing the plugin, rebuilding the project, and starting the server. I went to edit a content that had a rich-text field and as soon as it was rendered It crashed the site and the screen was completely white(nothing was rendered) with the following error in the console:

Error: The language "markdown" has no grammar

Versions: @strapi/strapi: ^4.3.6 strapi-plugin-wysiwsg-react-md-editor: ^4.2.0

Any recommendations on what might have been wrong or how to fix it?

Experiencing the same issue.

I'm getting the very same error with "strapi-plugin-wysiwsg-react-md-editor": "^4.2.0" and "@strapi/strapi": "^4.4.5" .

@kwiat1990 I have just tried "@strapi/strapi": "4.4.5" and "strapi-plugin-wysiwyg-react-md-editor": "^4.2.0" can run successfully

What is the node version you are using? Can you provide a minimal repo for me to check?

Also please install with npm install strapi-plugin-wysiwyg-react-md-editor, there was a typo in the package name

Hi @kwinyyyc, I use node 16.4.2 and this is my package.json:

{

    "@strapi/plugin-i18n": "^4.4.5",
    "@strapi/plugin-users-permissions": "^4.4.5",
    "@strapi/provider-email-nodemailer": "^4.4.5",

@kwiat1990 I tried the above config with node 16.4.2 still cannot replicate the issue, would be great if you can create a repo that can replicate the error.

Well, on the fresh installed and barebone Strapi instance it does work. What's more interesting, with all other plugin I have defined in plugins.js, it seems to be working as well, although they not used and perhaps this make some difference.

Interesting, does it mean it only happens on your live environment? Even if you try to create a new strapi instance with all the same plugins, the error won't show up?

[kwiat1990]

Not exactly. All the plugin are installed and configured but they're not connected to the same systems, e.g. Postgres, Cloudinary etc. In the fresh instance I used SQL database and didn't really connected to mentioned systems. Additionally, I didn't had my existing content-types and the actual content, so it's also a factor.

Experiencing same error with Strapi 4.5.2, installed plugin and it doesn't work on my dev environment.

[kwinyyyc]

I am trying to see if prebuilt the MD editor in common.js would work, published a beta version strapi-plugin-wysiwyg-react-md-editor@4.3.0-beta.2, can you give it a try? @minht11
