dap-lldb: Wrong type argument

[tastytea]

I'm trying to debug a C++-project with lldb-vscode, but all I get is if: Wrong type argument: stringp, nil in the *Messages* buffer after running dap-debug . When I run dap-debug with my real config (not the minimal init.el from below), I get apply: Wrong type argument: stringp, nil.

Configuration

GNU Emacs 27.2, all packages freshly upgraded to the newest VCS versions. lldb version 12.0.0 (was the same with 11) OS: Gentoo Linux

Minimal init.el

;; Bootstrap straight.
(customize-set-variable 'straight-repository-branch "master")
(defvar bootstrap-version)
(let ((bootstrap-file
       (expand-file-name "straight/repos/straight.el/bootstrap.el"
                         user-emacs-directory))
      (bootstrap-version 5))
  (unless (file-exists-p bootstrap-file)
    (with-current-buffer
        (url-retrieve-synchronously
         "https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
         'silent 'inhibit-cookies)
      (goto-char (point-max))
      (eval-print-last-sexp)))
  (load bootstrap-file nil 'nomessage))
(require 'straight)

(straight-use-package 'dap-mode)
(customize-set-variable 'dap-lldb-debug-program "/usr/bin/lldb-vscode")
(require 'dap-lldb)

launch.json

Here is a minimal C++-project to reproduce the issue: daptest.tar.gz. Run cmake -S . -B build followed by cmake --build build and then M-x dap-debug.

Hi guys. I have similar issue with gdb (doom-emacs/Linux)

and dap-debug fails with the default configuration

Most likely delated to the discussion at https://github.com/emacs-lsp/dap-mode/pull/529

Should this be fixed since the PR was reverted?

I am also having this problem, even though I just recently copied the latest version of the repo into the melpa package location on my machine. Any tips on resolving it?

I have the same problem with dlv for golang

UPD: I solved the problem by removing the "+lsp" (debugger +lsp) file init.el of my Doom Emacs
