Getting "Error: 414 URI Too Long" until restart of vscode

[dannief]

I am having an issue of inconsistent behavior of the plantuml extension.

I have plantuml files with both a URL include and local includes. (See below). The files render the first 2 times when selected in the vscode explorer. However, after the third or fourth time selecting the files. I get Error: 414 URI Too Long (see below) and I have to restart vscode in order to render these files again.

These are my environment details:

OS: Windows 10
vscode: v1.56.1
plantuml extension: v2.14.5
PlantUML server: Docker image plantuml/plantuml-server:jetty-v1.2021.5

Based on the resolution of this issue https://github.com/qjebbs/vscode-plantuml/issues/260, I believe that the plugin supports POST requests to a local plantuml server with include support. But it seems it is using GET request instead at the time the error occurs.

Is there a way to see the extension logs to investigate further?

There's something we can do to improve in this case.

Currently,

if the server fails to response to POST one time, falls back to GET for good (where Error: 414 URI Too Long comes from)

Should change to,

If the server response to POST well at the first time, stick to use POST and ignore errors

PR is welcome.
