PlantUML diagram generation with Kroki is broken again

thetric commented 3 months ago

Observed vs. expected behavior

The preview does not render the diagram:

Neither the public Kroki server nor our selfhosted one does work. The IntelliJ logs do not include any errors regarding the generation

Steps to reproduce

Enable Kroki and create the following file:

[plantuml,datafields]
----
object "<datafields>" as s {
}
object "<datafield>" as df

s *-- "0..1" df
----

Sorry this is not working for you. I tried to reproduce it locally, still this is what I see, using the official

Can you please provide a larger example where this is failing for you? Do you have an example in a public Git repository? Maybe an AsciiDoc attribute setting is conflicting?

Hm, I guess it is more an issue with our server configuration, Kroki itself or asciidoctor-kroki. When forcing the value of kroki-http-method I observed two different behaviors:

get: the SVG is invalid and contains the Kroki index.html. I guess that is the same behavior I see in IntelliJ.

This issue can be reproduced using this example: antora-repo.zip

thetric commented 2 months ago

POST is broken in asciidoctor-kroki: https://github.com/asciidoctor/asciidoctor-kroki/issues/448

thetric commented 2 months ago

Insofar not an issue with this plugin but with asciidoctor-kroki? I am not sure how these two relate, so feel free to close this issue

Thank you for providing the example. I extracted it and tested it locally. For me it works as expected:

The preview in the IDE shows the diagram
When I render it use the Antora CLI using "yarn build" the image is there

I left it with the defaults which were set to "GET" in your config.

I'm using plugin 0.43.1 on IntelliJ 2024.2.1 RC.

Also tested plugin 0.41.6 and 0.42.2 on IntelliJ 2024.1.6

I received the same issue where diagrams would not generate . Deleting the /.idea folder in my project and re-loading the folder as a new project solved it. After the .idea folder was regenerated it was sorted. What in the folder was bad, I'm not sure.

Since you're able to create a new example project this might not be your issue, but starting from a fresh project might help although you'll be stuck setting it back up again. Clearly back up your current folder.

System - Win11, WSL docker compose of Kroki 0.25.0 PyCharm 2024.2.1 Plugin version 0.43.1

Aha! My issue came from a misconfigured proxy before Kroki

asciidoctor / asciidoctor-intellij-plugin
