2 years ago It's probably because Excalidraw is a verbose textual format. You got an HTTP Error 414 (URI Too Long) from kroki.io (or your kroki instance) right?
You can change the max uri length using the KROKI_MAX_URI_LENGTH environment variable. See: Kroki Documentation - Max URI length
I tried your diagram on an local Kroki instance with KROKI_MAX_URI_LENGTH=64000 and the diagram renders like your example in the issue.

2 years ago Still doesn't work for me :( Where can I find log files or the http error, as I don't see any 414 error.
I'm starting the excalidraw docker with this:
docker run -p:8004:8004 -d --restart unless-stopped --env-file /etc/kroki.env yuzutech/kroki-excalidraw
Here is the contents of /etc/kroki.env:
KROKI_BLOCKDIAG_HOST=192.168.80.45
KROKI_BLOCKDIAG_PORT=8001
KROKI_MERMAID_HOST=192.168.80.45
KROKI_MERMAID_PORT=8002
KROKI_BPMN_HOST=192.168.80.45
KROKI_BPMN_PORT=8003
KROKI_EXCALIDRAW_HOST=192.168.80.45
KROKI_EXCALIDRAW_PORT=8004
KROKI_MAX_URI_LENGTH=640000

2 years ago @rrrevin you should define the KROKI_MAX_URI_LENGTH environment variable on the gateway server (i.e., yuzutech/kroki).
The companion containers (such as yuzutech/kroki-excalidraw) do not check the max URI length.

2 years ago I did that as well. This is the docker startup for the main server; they all reference the same env file:
docker run -p8000:8000 -d --restart unless-stopped --env-file /etc/kroki.env yuzutech/kroki

2 years ago Figured this out. Turns out there were two issues. The one you pointed out above (KROKI_MAX_URI_LENGTH) and a system that came up with the same IP as the kroki server.
All working now. Thanks all.

2 years ago Glad you figured it out! 👏🏻
Unfortunately, I think we cannot log an explicit message because the max URI length check is somehow "low level". I think the exception is thrown by Netty (the underlying network library used by Vert.x):
I will dig a bit further to see if we somehow can catch the 414 error in order to print a friendly error message (we could even suggest to increase the max URI length using the KROKI_MAX_URI_LENGTH environment variable in the error message).
I'm using wiki.js with the kroki add-in enabled. I can get a ton of diagrams working, but this one will not render. It was created using the excalidraw website itself (https://excalidraw.com). But when I try to render it using the kroki excalidraw docker image.. it fails. All of my other excalidraw diagrams work using the same docker.. just this one doesn't.
Don't know where to find logs to help unfortunately, I just know I get nothing back from the docker for this one diagram. Anyone have an idea?
It should look like this:
