Use dap-codelldb get deserialization error but works for VSCode.

[zw963]

I tested dap-codelldb on a Crystal lucky project recently. it works on my arch linux with lldb/llvm 18.1.18, crystal 1.13.2, codelldb plugin version 1.10.0 on VSCode 1.93.1

Following is screenshot.

.vscode/launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "lldb",
            "request": "launch",
            "name": "crystal: debug current file",
            "preLaunchTask": "crystal: build current file (debug)",
            "program": "${workspaceFolder}/bin/website",
            "args": [],
            "cwd": "${workspaceFolder}",
            "initCommands": [
                "command script import /home/zw963/Crystal/crystal-lang/crystal/etc/lldb/crystal_formatters.py"
            ]
        }
    ]
}

.vscode/tasks.json

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "crystal: build current file (debug)",
      "type": "shell",
      "command": "crystal build --debug src/website.cr -o bin/website"
    }
  ]
}

Then, i tried it use emacs with dap-codelldb, like following.

(setq dap-utils-extension-path (expand-file-name ".extension" (file-name-directory (or load-file-name buffer-file-name))))

(setq dap-codelldb-extension-version "1.10.0")
(require 'dap-mouse)
(require 'dap-ui)
(require 'dap-mode)
(require 'dap-codelldb)

After run dap-debug, select the configuration template crystal: debug current file, wait it build successful, then, i get error message like following:

/home/zw963/Dropbox/common/.emacs.d/plugins/dap-mode/.extension/vscode/codelldb/extension/adapter/codelldb --port 17977
[ERROR codelldb::dap_session] Deserialization error: data did not match any variant of untagged enum ResponseResult at line 1 column 84

i don't understand dap well, i guess the issue is, emacs dap-codelldb not respect my following initCommands config, right?

 "initCommands": [
                "command script import /home/zw963/Crystal/crystal-lang/crystal/etc/lldb/crystal_formatters.py"
            ]

Thanks
