Failing to preview diagram (Alt + D) [VSCode 1.27.2]

Hi,

Preview diagram is failing on VSCode 1.27.2, it reports me the following error: Unable to open ‘PlantUML Preview’: resource is not available.

I’ve been digging about this (originally I though this was some bad configuration), but then I stumbled upon this comment stating that vscode.previewHtml is deprecated. So, I decided to take a look on extensions’ source code and found this. I tried to debug this to confirm this is what’s really causing the issue, but I’m a complete JS noob and couldn’t get to debug anything 😄 (.NET is my world 😉 )

Can you please tell if this is really an issue?

Thanks for your attention! 🙂

Encountered the similar issue today (not sure if it’s the same cause). VSC version 1.27.2 on MacOS 10.13.6. PlantUML plugin version: 2.9.3 Java version: 1.8.0_181-b13

prompt: Unable to open 'PlantUML Preview': resource is not available.

The export function doesn’t work either. not sure if it is related. The output:

TypeError: Cannot read property 'uri' of undefined

tried specifying java and plantuml.jar location, reinstall graphviz, doesn’t help.

The command java -jar plantuml.jar test.wsd in the terminal works. (with the latest version of plantuml.jar downloaded from plantuml.com)

Thanks.
