Kroki Server returns 414 Request-URI Too Long #345

Closed achimgrimm closed 3 years ago

achimgrimm commented 3 years ago

Once a diagram gets bigger (very common for some diagram types like BPMN), the request to the kroki server will result in a very large URI if HTTP GET is used.

This will result in the error message Failed to generate image: 414 "Request-URI Too Long"

Increasing the max URI length limit on the kroki server is a not an option, as this will also not work with larger diagrams (i.e. normal sized BPMN).

Kroki server allows to use HTTP POST instead. see https://kroki.io/#how

I hadn't implemented automatic switching to POST yet indeed. Shouldn't be too hard to implement.
