Is Deno not supported as a debugging runtime environment?

[KrofDrakula]

I've been using VSCode to debug Deno programs and I've tried to use the debug visualizer to help with debugging, but I've been unable to get any expression to show in the debug visualizer when debugging:

The spinner in the top right just keeps on spinning regardless of which expression I try using in that context.

Does the debug visualizer support the Deno runtime, or am I barking up the wrong tree?

Here's the launch.json file for completeness:

{
  "version": "0.2.0",
  "configurations": [
    {
      "request": "launch",
      "name": "Launch Program",
      "type": "node",
      "program": "${file}",
      "cwd": "${workspaceFolder}",
      "runtimeExecutable": "deno",
      "runtimeArgs": ["run", "--inspect-brk", "--allow-all"],
      "attachSimplePort": 9229
    }
  ]
}
