Weird error when URI is too long

[OlivierJourdan]

I'm using this command on a file that contains a very large PlantUML diagram (File --> 062.adoc.txt)

.\asciidoctor -a diagram-server-url=https://kroki.io/ -a diagram-server-type=kroki_io -a kroki-fetch-diagram -r asciidoctor-kroki "C:\Users\team\Desktop\Large output\Includes\062.adoc"

I'm suspecting that the URI is too large but I get the following error:

asciidoctor: FAILED: C:/Users/team/Desktop/Large output/Includes/062.adoc: Failed to load AsciiDoc document - undefined method `request_post' for Net::HTTP:Class

    res = ::Net::HTTP.request_post(uri, data)
                     ^^^^^^^^^^^^^

Use --trace to show backtrace

The thing is that I was thinking that using the kroki-fetch-diagram attribute should have prevented this kind of error. What am I doing wrong or what I don't understand?

@OlivierJourdan Are you using Ruby > 2.4 ?

[OlivierJourdan]

Yes, Ruby 3.1.2.

[ggrossetie]

Oh I remember now, it was fixed in 242ca5d but I need to release a new version.

[OlivierJourdan]

Good to know there is already a fix 👍

Question: Why does the error only appears on a large diagram? (I don't understand the fix 😅).

[ggrossetie]

Question: Why does the error only appears on a large diagram? (I don't understand the fix sweat_smile).

You can take a look at: https://docs.kroki.io/kroki/setup/configuration/#_max_uri_length and https://github.com/Mogztter/asciidoctor-kroki/tree/ruby-v0.5.0#configuration

Basically, there's a URI limit so when the size exceed 4000 characters we switch to POST (instead of GET)

[OlivierJourdan]

Thanks for the hint.

[ggrossetie]

@OlivierJourdan Just released version 0.6.0, could you please give it a try and report back if you have any issue?

[OlivierJourdan]

It's working like a charm 😄
Thanks for the really quick support 👍

A subsidiary question, for PDF generation I'm using the following command asciidoctor-pdf -a diagram-server-url=https://kroki.io/ -a diagram-server-type=kroki_io -a allow-uri-read=true -r asciidoctor-kroki "C:\Users\team\Desktop\Large output\Includes\062.adoc" the generation is not failing but I don't get the image.

The output says:

Does the kroki-http-method attribute can solve this? (I'm going to test).

[OlivierJourdan]

Does the kroki-http-method attribute can solve this? (I'm going to test).

No, it's not working. As far as I understand, ascidoctor-pdf is reading the URI and getting the error. I should look at asciidoctor-pdf documentation.

[ggrossetie]

I see two issues:

• 414 URI Too Long -> kroki-http-method should be adaptive (default value) and you can play with kroki-max-uri-length to switch to POST
• asciidoctor: ERROR: cannot fit formatted text on page -> not sure why...

That's strange because Kroki server says that the request URI's length exceeds 4096. If URI length exceeds 4000 we should be using a POST request:

https://github.com/Mogztter/asciidoctor-kroki/blob/0667f6313ea97871292d6ab1f25b30b43eea03e5/ruby/lib/asciidoctor/extensions/asciidoctor_kroki/extension.rb#L359-L367

I don't get why we are using a GET request...
Does it work if you configure kroki-http-method: post ?

[ggrossetie]

OH I see, you need to add kroki-fetch-diagram=true otherwise it will use a GET request (since we don't download/fetch the diagram from Kroki).

The following command should be enough:

$ asciidoctor-pdf -a kroki-fetch-diagram -r asciidoctor-kroki doc.adoc

Sorry for the delayed reply, I was not able to test anything until now.

You're right $ asciidoctor-pdf -a kroki-fetch-diagram -r asciidoctor-kroki doc.adoc is working fine. I came to use a different command due to the issue with png file generation on windows (#369). Note that I'm not sure it was related, but this is where I ended up.

So,

1. I can confirm that I can generate a large document (17+ Mb for the PDF) in PDF or HTML format with the same attributes in the command
2. I guess that the v0.6.0 also fixed Png file generation issue #369. In any case, I could have generated each format (with png and SVG files) twice w/o issues with the images generated. Note that the second generation is much faster as far as the existing images are not fetched if I correctly understood the fix.

Long story short: everything is working! Thanks for your quick and efficient help 🙇‍♂️ 👍

I think the issue can be closed.

Thanks for your input!

Note that the second generation is much faster as far as the existing images are not fetched if I correctly understood the fix.

If the file already exists on disk it should not fetch again from Kroki. I believe that's why it's faster.

I think the issue can be closed.

I will keep it open since I think we should add a note in the documentation on how to resolve/workaround the error "414 Uri Too Long".

Please also document explicitly that GET will always be used as long as kroki-fetch-diagram is not set, even though kroki-http-method is set to post or adaptive (with very long URL).
Took me quite a bit to find out ...
