Mermaid code blocks in markdown showing error #21427

Closed dvjn closed 2 years ago

dvjn commented 2 years ago

Description

When I create a mermaid code block in a markdown file, error banners are shown on each character input. Also, in the preview tab, the height of the mermaid diagram is broken.

This is working properly on v1.17 but breaking on dev.

Stacktrace:

22:32:03.497 Uncaught Error: Language id "vs.editor.nullLanguage" is not configured nor known

Seems this is a bug introduced in Monaco 0.34: https://github.com/microsoft/monaco-editor/issues/2962.

I don't think we can do anything about it until it's fixed upstream, at best, we could filter out this specific error message or downgrade Monaco.
