Previews shows "No valid diagram found here!" all the time (startup issue)

See original GitHub issue

Here is what I found after some lookup in all logs (found in Log (Window)):

This happens on startupt of vscode, then any diagram shows “no valid diagram found here!” without generating any log anywhere

UPDATE: if it can help, the generate URL for current diagram does generate correct URL, but I guess it doesn’t make use of the same stuff under the hood…

As mentioned here, try to put the cursor somewhere between @startuml and @enduml, and then press ALT + D to open the preview. If the cursor is outside of the @startuml @enduml block, the “No valid diagrams found here!” error occurs.

@mrseanryan This is related to the Markdown security restrictions in VSCode

https://code.visualstudio.com/docs/languages/markdown#_markdown-preview-security

I have not found a way, as of yet, to set this setting via settings.json for the user or workspace.

– Edit

You can force this dialog by running the command Markdown: Change Preview Security Settings in the omnibox.
