lldb-dap for VSCode ignoring env

[nashiradeer]

The lldb-dap VSCode's extension isn't setting the environment variables from my launch.json.

{
  "type": "lldb-dap",
  "request": "launch",
  "name": "Debug (lldb-dap)",
  "program": "${workspaceFolder}/target/debug/hydrogen",
  "preLaunchTask": "rust: cargo build",
  "cwd": "${workspaceRoot}",
  "env": {
    "RUST_LOG": "hydrogen=trace",
  },
}

I think that some context needs to be provided, I'm using lldb-dap on a Dev Container created with rust:1.84.0-alpine3.21 image, using lldb-dap from Alpine 3.21 repositories.

Support for the env dictionary was only implemented recently in #106919. This commit is not yet in LLVM-19 release and will only be part of the LLVM-20 release. Which version of LLVM / lldb-dap is installed via the Alpine 3.21 repository? I have a gut feeling that lldb-dap is simply too old.

Before #106919, the syntax was

"env": [ "RUST_LOG=hydrogen=trace" ],

instead of

  "env": {
    "RUST_LOG": "hydrogen=trace",
  }
