VSCode debugger breaks on unknown command

For reasons unknown to me, the VSCode Julia debugger stopped working, and now it gives this error message every time I try to debug:

  Activating project at `~/Julia/JuliaCheck`

I tried removing and re-creating .vscode/settings.json, as mentioned in another thread, but it did not help.

The line ERROR: Unknown command: stop used to say simply ERROR: Unknown command, but I edited the relevant file just to print which command is the “offending” one.

I am using these versions:

  • VSCode: 1.99.3
  • Julia: 1.11.5
  • It seems to me that the version of the VSCode extension is 1.127.2, if I’m reading it right in the error message.

I use VSCode for Windows and connect to WSL, where I run the project. However, I tried running it directly on Windows with the same result.

Solved: it was just that I forgot to update .vscode/settings.json after creating a src/ subfolder and moving the “executable” file in there.

Of course, this is a very silly error, but it is worth noting that there is no clue about the nature of the problem in the output message. Nothing along the lines of “file MyScript.jl not found”.
