First, sorry if I am not at the right place to ask. I am hesitating to post here or directly on https://manuelhentschel.github.io/vscDebugger/index.html.

I have this config in debug.lua:

        dap.adapters.r = {
            type = "server",
            port = "18721",
            name = "R",
            executable = {
                command = "R",
                args = { "--slave", "-e", "vscDebugger::.vsc.listenForDAP()" },
            },
        }

        dap.configurations.r = {
            {
                type = "r",
                name = "Debug R-File",
                request = "attach",
                debugMode = "file",
                stopOnEntry = false,
                enableVariablesPanel = true,
            },
        }

There after, I am opening an R script, set a brakepoint and type :lua require"dap".continue() to launch a debugging session. I am getting this error:

Source not available, cannot jump to frame

I further explored the .cache/nvim/dap.log and it looks like there is communication going on.

Anyone has an idea what is going on?

Thank you,

You get this message because the stackframe returned by the debug adapter has no source:

{
  body = {
    stackFrames = { {
        id = 0,
        name = "Global Workspace",
        presentationHint = "label"
      } },
    totalFrames = 1
  },
  command = "stackTrace",
  request_seq = 7,
  seq = 0,
  success = true,
  type = "response"
}

so the client has no idea where it should jump to on the stopped event. That's why you're getting the Source not available, cannot jump to frame message.

Sounds like an issue with the debug adapter. I'm not aware of anything the client could do to handle such responses differently
