Mermaid charts are loading irregularly in the public API

[scali]

Quite same as #1443, but a bit different

Going to kroki.io and to samples of Mermaid chart. Going to the link of the diagrams directly (Sequence Diagram or Gantt) :

For example, this link :
https://kroki.io/mermaid/svg/eNpljzFuwzAMRXefgtlrZzcKBymCtMjQoTegZdYiwoqqTLfw7SMrSDKEi4j_H6nPaqLfmYKjA-OY8KeCXBGTseOIwWAv7OhJfdO-aMWtu5P60MIHiSis_Qt4_QdMBIvOu0KKaswEinnnyZ2LuNbK3zYcefQGOCKHycAvUZ3XMCTGglMYyvupRpAKq99wHf1CYw0oYF7n7Ezw2qdtFxP9IUvTNNX9s7orsVt4T4S2eRhdPiufsUbvdbZH-KzXt4wnFVlgVB021QUIImOl

took from the offical page of exemples of kroki.io

The link loads irregularly, and when it failed, there is this message :

Convert plain text diagrams to images !
🤖 bip... bip... something wrong happened!
400 Error: An error occurred while converting the diagram

I'm using kroki to load images in a asciidoctor/antora document and have the same kind of error :

I'm getting this exact issue. Just got to know about Kroki! and the AsciiDoctor extension and was going mad about not understanding how unpredictable the extension seemed. Turns out (as op points out) it's the Kroki Mermaid endpoint.

FYI: With GraphViz it's working consistently.

As I have this option, I've ended up by deploying a self managed version of Kroki, as described here, and setting the kroki-server-url parameter in the playbook configuration file (antora-playbook.yml)

asciidoc:
  extensions:
  - asciidoctor-kroki
  attributes:
    kroki-fetch-diagram: false
    kroki-server-url: https://kroki.my-company.domain

The service run nicely and the charts are loading now.

Maybe the public site of kroki.io is sometime overloaded.

I'm now getting this error consistently. Can we get an update on ETA to fix?

[ggrossetie]

Should be fixed now.

[Brianwind]

getting the same problem now, even the example in the website failed.

I just deployed a new version that includes #1745. It's not perfect but hopefully it should improve Mermaid's reliability.

Please open a new issue if you are still experiencing issues. If possible, please include the time range during which you observed instabilities. It greatly helps troubleshooting 😄
