Hi! Recently:ish I have been getting this error alot. When I try to preview something unsaved and for alot of different files.

I am not sure what the problem might be. Any tips / ideas?

Preview seems to not work with files with no folder/workspace

I have been playing around trying to get some consistent repro, and it seems that

anytime I try to preview a file that I have just opened "solo" - i e not within a folder or project, I get this error.
Also happens if I have a project / folder open and open/drag a file into vs code that is not within the opened project/folder.
There is no connection to the diagram source itself, this issue is caused by "setup factors".

Happens for the simplest of tests, e g

@startuml
a -> b: msg
@enduml

Error:

Update

I have not played around extensively with this error, but it is still there.

Similar (fixed) issue: #149. Seems to be similar issues for other vs code plugins (example: cpptools ), again, I have not investigated.
