Preview not updating

[tpotter7]

I'm running on Windows 10 Pro. I'm using VSCode 1.42.1. I'm using the PlantUML 2.13.6 extension. When I initially select Preview for my puml file, it shows the diagram just fine. Then, when I make updates the diagram does not update. If I re-select preview, the diagram does not update. If I close the diagram window and select preview, the preview will not open. Alt-D provides the same results as if I select "PlantUML:Preview Current Diagram" from the Command Pallet. The only way I can get the diagram to update is to re-start VSCode, load the puml file, and select to preview the diagram again.

I just remembered that a very small percent of the time, the diagram will update once or twice as I'm editing the puml file, then it stops updating and the above described symptoms occur. The much more likely scenario is that it never updates after being initially drawn. It is like it gets stuck and then just never responds to change/update requests after that.

What can you see in Help - Show Developper Tool or somthing like that?

[tpotter7]

Not sure I understand your question. Are you looking for VSCode console log output? If no, please let me know what you are looking for. VSCode does not have the menu you mention below. If yes, I see the following errors showing up in the log after the diagram freezes and stops updating:

[Extension Host] rejected promise not handled within 1 second: SyntaxError: "c:/Users/tpotter8/Documents/DOJ/UML/4-Eligibility%20Check.puml" is not a valid JSON Schema. [Extension Host] stack trace: SyntaxError: "c:/Users/tpotter8/Documents/DOJ/UML/4-Eligibility%20Check.puml" is not a valid JSON Schema at c:\Users\tpotter8.vscode\extensions\arjun.swagger-viewe-2.2.2\node_modules\json-schema-ref-parser\lib\index.js:114:19 [[object Object]]"c:/Users/tpotter8/Documents/Projects/DOJ/UML/4-Eligibility%20Check.puml" is not a valid JSON Schema SyuntaxError: "c:/Users/

This same set of console log messages repeats as I edit my puml file but the diagram does not update with the edits. If I close VSCode and re-open it, the diagram repaints and it has all my updates with no errors. It will then update as I edit for a random amount of time (maybe 1-10 updates) and then it freezes again.

So, I uninstalled the swagger viewer and tested again. Now it still does not update the diagram as I make changes but will if I restart VSCode. In the console, there are no error messages anymore. Everything else works. I can export and do other things. It is just that the diagram does not update and is frozen. Even if I close the preview window and select preview diagram again from the command pallet, it does not show the diagram (until I close and reopen VSCode).

Same problem on Fedora 31. No error log found in the developer console.

[gdbapi]

Hello, Same issue than tpotter7 and same behaviour on all tries But since VSCode 1.44.1 when I re-select preview (or Alt+D) it generates a new preview in the preview window (it's better than nothing)

[coderbean]

I finally solve this problem, now ext is working fine!

1. uninstall plantuml in vscode
2. clean files rm -rf ~/.vscode/extensions/jebbs.plantuml-2.13.12
3. reinstall pluanuml ext in vscode

[tpotter7]

Thanks for the update. Unfortunately, that did not work for me:-(

I am experiencing exactly the same issue: VSCode: 1.27.1 PlantUML extension: 2.13.12

I'm having similar issue - even with ServerSide rendering, this didn't help.

I can only copy paste the uml code to the localhost:8080/ then I can see the preview there

[ntmggr]

Experiencing the same with

• VSCode: Version: 1.51.1
• PlantUML extension 2.13.16

It does not work also with external server rendering

[qjebbs]

Still cannot reproduce here.

Can you guys try disable all other extensions except plantuml? I've ever encounter a extension conflict case.

The last tip, if any of you are capable to coding, you can clone and debug right in your environment, it's so much better than we guess where the problem is.

[Matjaz-B]

I'm experiencing the same issue. All other extensions are disabled. Behaviour is the same if using local or server renderer

First time after opening VSCode preview works. The after some time (e.g. after some error is shown or after few updates) preview does not update. If preview window is closed then i can not reopen preview. After VSCode restart is works the same way. Closing/openin file does not solve the issue.

Export of diagram works in all cases.

• running on windows 10
• VSCode version 1.53.2
• PlantUML extension 2.14.3

Hi @Matjaz-B - I managed to get around this issue by running a Docker container running as a server (instruction here:https://github.com/plantuml/plantuml-server). Once it's up and running, you'll need to set this up on VSCode telling it to use the IP and port of that container.

I never had same issue since

[Matjaz-B]

Hi @ele0nard, I was testing with public server and behaviour was the same. With local server issue should be gone?

[ele0nard]

I run it locally yes - i just ran this

docker run -d -p 8080:8080 plantuml/plantuml-server:jetty

[sba923]

Same here. Have to close VS code and launch it anew. How can I enable logging so that I can troubleshoot what's going on?

I was able to get it working after downloading the latest Java SDK and GraphViz. I used the information found here: https://www.rushis.com/plantuml-with-vscode/

Didn't fix anything for me.... 😭

[nleroux-bunnings]

Same happened for me until I put back the directives @startuml and @enduml at the start and end of the code

Recently I had the same issue, updating VS Code solved my issue

[erosenov]

I resolved the problem by installing JRE x64.
