  Ask an AI to write Nim code for you.

  You also have https://learnxinyminutes.com/docs/nim/, which is a nice resource to get some of the syntax if you're already familiar with other languages.

  Any particular library you lack documentation for?

  The error is way to vague. You need to post some code at least. Try to make it a minimal example. That way someone can at least look at what the issue could be.

  Have you succesfully written some no-gui samples? First start with minimal test-projects in a bottom-up way, and then you can do the harder stuff. Also the lib-docs have a great search function which i use a lot.

  Starting with jester is not the easiest way to get going. However, for me the following youtube-movies got me going...

  I use now json2web as a base for jester-programming (but is not complete in any way):

  Use python code and ask ChatGPT v4 to convert it to Nim. Sometimes it makes mistakes, but that's good for learning to discover and fix them. Don't start learning Nim with web/servers/io.

  Jester is a tricky one. It is super easy to use, when it works, then all of a sudden it doesn't and there is barely any documentation.

  Maybe try HappyX or any of the other more recent developments in the web-server space? nimble.directory is a good place to search for packages.

  You might've run into this bug: https://github.com/nim-lang/Nim/issues/21422. Maybe try passing the flag which makes Jester use the standard library http stuff.

  I'd like to point out https://nim-by-example.github.io is also a pretty good resource for beginners since the examples are short and well organized, and thus you can quickly get a feel for the language.
