nvim-dap with LLDB does not stop at breakpoint after sending input into stdin?

[nyngwang]

My config:

  dap.adapters.codelldb = {
    type = 'server',
    port = "${port}",
    executable = {
      command = vim.fn.stdpath('data') .. '/mason/packages/codelldb/codelldb',
      args = {"--port", "${port}"},
      -- On windows you may have to uncomment this:
      -- detached = false,
    }
  }
  dap.configurations.cpp = {
    {
      name = "Launch file (lldb)",
      type = "codelldb",
      request = "launch",
      -- required fields.
      cwd = '${workspaceFolder}',
      stopOnEntry = false,
      -- setupCommands = {
      --   {
      --     text = '-enable-pretty-printing',
      --     description = 'enable pretty printing',
      --     ignoreFailures = false
      --   },
      -- },
      program = function()
        return vim.fn.input('Path to executable: ', vim.fn.getcwd() .. '/', 'file')
      end,
    },
  }

What do those R symbol mean?

lol I'm stupid I didn't even know that I should "compile with debug symbols". I just saw your kindly comment somewhere and it works:

Did you compile your program with debug symbols? There is a message indicating that it can't set the breakpoint.

message = "Module containing this breakpoint has not yet loaded or the breakpoint address could not be obtained.",

Regarding my second question about the meaning of R was explained there:

[...]

Actual Result

The debugger runs through the entire program, exits, and does not stop at the breakpoint. After the execution ends, the breakpoint symbol becomes R (rejected), instead of B.
