Starting a repl fails with Windows WSL extension enabled

[kyle-howley]

The error is "ERROR: Unhandled REPL handler exception processing message {:op eval, :code ns, :id 1}"

It happens when executing the "fire up a getting started repl", or when trying to use jack-in with a project.

Thanks for reporting! Can you give us some details about your machine, os, VS Code version, and such? What do you see in the Jack-in terminal? The REPL/Output window logs a few things during this process, and it would be good to know what you see there as well.

Windows 10, VS code version 1.82.2, calva is a fresh install.

In the terminal I see:

⚡️ Starting the REPL ⚡️ using the below command line:
pushd c:\Users\KYLEHO~1\AppData\Local\Temp\betterthantomorrow.calva\0mnsud & java -jar ".calva\deps.clj.jar" -Sdeps "{:deps {nrepl/nrepl {:mvn/version,""1.0.0""},cider/cider-nrepl {:mvn/version,""0.28.5""}}}" -M -m nrepl.cmdline --middleware "[cider.nrepl/cider-middleware]" & popd
nREPL server started on port 64046 on host kubernetes.docker.internal - nrepl://kubernetes.docker.internal:64046
ERROR: Unhandled REPL handler exception processing message {:op eval, :code ns, :id 1}

and in the jack-in window I see:

This seems to happen in a docker container. Can you describe a bit around that setup?

[kyle-howley]

I'm not sure how to find that information. Calva appears to be trying to start a docker container, but I am but I am not using docker for any project. I tried a standard test project using the "https://github.com/seancorfield/deps-new" tool and started a project (deps.edn, build) repl, but it failed with the error above. I tried without creating a project at all and using calvas in-built "fire up a getting started repl" command and it is throwing the same error. So I assume Calva is using docker...

I fixed the issue by disabling the Microsoft official WSL extension in vs code.
