Weird Error when debugging mlr3oml

[sebffischer]

Describe the bug Debugging mlr3oml does not work but gives the error that is printed indefinitely:

Error in `[[.R6`(list, entry) : 
  R6 class RootNode/MetaNode/Node/R6 does not have slot 'variablesReference'!
8: `[[.R6`(list, entry)
7: list[[entry]]
6: lget(self, "variablesReference", 0)
5: session$rootNode$findChildNode(list(findBy = "varRef", varRef = varRef))
4: variablesRequest(response, args, request)
3: .vsc.dispatchRequest(obj)
2: .vsc.handleJson(json)
1: vscDebugger::.vsc.listenForJSON(timeout = -1)

To Reproduce Steps to reproduce the behavior:

1. Clone mlr3oml into ~/
2. Open mlr3oml as a project in VSCode
3. Start "Debug R-Package".
4. The error as shown above arises and is printed indefinitely.

Your Launch config Default configurations for both cases, i.e. "Debug R-Package".

Expected behavior I expect to not get the error message and be able to debug the package.

Actual behavior The error message, as shown above, is printed indefinitely in the Debug Console.

Desktop (please complete the following information):

• OS: WSL: Ubuntu-20.04 (via VS-Code Remotes Extension)
• R Version: 4.1.1
• vscDebugger Version: 0.4.7
• vscode-r-debugger Version: 0.4.7

Additional context The above-described procedure works for other packages. Also only running __load_all() works for mlr3oml__.

I think I figured out why this happens. It seems that the whole package is being loaded with load_all() with the default helpers = TRUE. In this specific case, loading the helpers causes an issue. It would be appreciated if this could be specified in the settings.

Does https://github.com/ManuelHentschel/vscDebugger/commit/ce8f2489ecc45750a1142af5fb202c5e6a651448 change anything?

Sorry, I forgot to answer and switched to neovim shortly after.
